Swap Harness Modification

[LS1ow]

Trying to work the final interior wiring demons out and its pretty close but i need some help.

99 Z28 originally a M6, being swapped to A4.

Pedals have already been swapped to auto pedals. Will be using a stock 4L60e shifter out of a 01 WS6. PCM and engine harness out of a 00 LS1/A4.

The switches at are my point of interest/trouble.

1. Stop Lamp Switch

Seems to be just plug and play. Same style unit as a M6 car. So we should be good here. If im wrong, let me know

Now, things start to get funky.

2. Clutch override switch
-Black/White & Grey wire 2 pin connector

Common sense says this is a 2 pin connector, to a regular "plunger" switch.
I should be able to just snip the connector off the wires and connect them together. Thus rendering the clutch override switch compressed all the time since the circuit is complete, therefor, itll start ! or crank atleast :lol:

3. Neutral Safety Swtich
-Green & Purple/White 2 Pin Connector

Same as the clutch switch no? if its a 2 pin connector, and its just a contact switch, wouldnt just connecting the 2 wires successfully by bass the switch?

HOWEVER, from what ive read, i can just snip the 2 wires and extended them to plug in to the A4 NSS. Pardon my stupidity, but i have not ever had to replace a NSS or mess with one on one of these cars, so were is it? is it on the shifter assembly ? or on the trans it self? Google gives me mixed answers. I have the shifter assemly i planned on used at home in a box, when i leave work ill swing by and open it up. See if theres any plugs or anything on it.

I know a NSS is a "safety" but honestly, you have to be a real buk buk buking idiot to start your automatic car in gear, so unless its needed to pass tech or anything, im okay with just jumping it. But if its something as simple as just extending some wires to a new plug, then may as well.

4. Reverse Lamp Switch
-brown & light green 2 Pin (Possibly, not 100%)

Folktale says that the Reverse lamp switch is on the side of the T56, which leaves me wondering what harness the reverse light switch is actually a part of? Is it on the dash harness or is it on the engine harness? I dont recall seeing any wires dropped down threw the shifter hole, or do they go threw on a grommet somewere?

I assume that on the A4 shifter i have boxed up, there will be some sort of contact switch on it for the Reverse lights. Which would allow me to just plug the existing reverse light switch into that switch and call it a day? Of am i just going to run a toggle for my reverse lights like there a light bar on my jeep???




Like i said earlier, im not really familiar with this stuff cus ive never had to do it. So ill be checking my shifter assembly i have to see if theres any plugs/switches on it. If there is that should answer some of my questions.

Brake light switch should be the same. The cruise stuff might be different but assuming no cruise? Don't know if the tcc switch is necessary either? What dash harness do you have? You shouldn't need to bypass both the nss and css. Nss should be on the shifter. Jumping either one will bypass it. I believe the rls is on the side of the t56 and off of the shifter on the a4. Bueno?

[LS1ow]

Opened up the box my shifter is in and it looks like it has a large switch assembly on it. Maybe a 6 or 7 pin flat connector. I'm assuming that's it. Looks like I'll be able to buy the pig tale and go from there, ya?

[sweetbmxrider]

Ya.

No cruise or TCS. Deleted all the stuff from the bay and am using the throttle cable you provided me.

I have the stock Dash harness in the car, so it's a M6 harness. I actually went ahead and jumped the CSS when I was at my garage just before. I'll have to find the pin out for the switch on the ****er. I'll just extend the wires for the NSS to there. I'll have to track down were the RLS switch wires are still.

[sweetbmxrider]

T56 might be part of the engine harness. I'm going to assume a little here, both dash harnesses usually have the css but its just unplugged. If you jumped it already, a nss won't function. If you leave it disconnected and wire up the nss, it'll function factory.

So if on a T56 car the RLS is on the engine harness, and on the 4L60e car it's on the Dash harness, I have to run the wires, 2 I'm assuming, from the switch to the PCM? Or would it be to the BCM?

And that is a good point Adam. If the CSS is by passed, it thinks the clutch is pushed in. And on a M6 car you can start "in gear" as long as the clutch is pushed in. Those of you with a M6 car, if the car is in nuetral, can you start it without having to press the clutch? I never had a M6 Fbody, but both my M6 S4 I had to press the pedal in regardless of were the shifter is. But that was a German car so who knows.

From what your saying Adam, I can unsplice the 2 wires for the CSS and leave them be if I run the 2 wires for the NSS to the corispinding pins on the new plug I have to get for the shifter switch

[sweetbmxrider]

The Light Green wire feeds the reverse lights directly through connector C400. Nothing to do with computer brah. I'm assuming here but the rls is definitely on the t56 and definitely on the shifter of the a4

An fbody only has a css so with clutch depressed, you can start in any gear.

Yes, do what I said if you want a functioning nss.

Which light green wire? Not the same green wire as the NSS correct ?

[sweetbmxrider]

The one you listed as number 4 but it'll be part of the large connector at the shifter.

[LS1ow]

oh, gotcha.

I just havent found that wire yet. As we said before, i think the RLS plug is part of the M6 engine harness. I dont have the M6 engine harness, so i have nothing to go off of. rendering me, lost.

Need to find the corresponding plug for this thing so i can get to wiring. It looks like the truck ones are different than the Fbody ones. And unfortunately i can only find the truck ones.

[sweetbmxrider]

Find a partout car? I think lt1/ls1/v6 shouldn't matter?

Thats what im trying to confirm now with my buddy that works for GM.


know of any cars with e 4L60e in it laying around that i can have at?:bertstare:

[sweetbmxrider]

Mine was a v6 and I did nothing with the dash harness, worked like factory. Unfortunately, that car doesn't have the harness you need....

confirmed that is is the same connector on all A4 4th gens, however it is discontinued. I can get it from napa, but the price is super steep for a plug. gunna see if anyone has one laying around

[PolarBear]

Do you have the part number? and Make?

[LS1ow]

Paul found me one in his parts castle and i picked it up last night. he indeed is the man.

Time to figure out the wiring!

womp womp

[LS1ow]

i got the above information from my buddy that works at chevy.

Now, round 2 of confusion. but lets start with the simple stuff.

A. "Ground" -Is this as simple as i really think it is? can i just throw an eyelet on the end and ground it to the chassis?

B. "Neutral Safety switch signal"- I take it this is the wire i extend the current NSS wiring to and just connect it? Assuming 1 is a signal and 1 is a ground on the M6 NSS, i would extend the signal wire to the new piece and then do what with the ground? leave it be?

C. "Ignition 3 voltage" - lolwut. Do i just tap this into some form of ignition on power source?

D. "Back up lamp supply voltage" - Since the car was previously a M6, and the Reverse light switch is on the trans, and the wires for it are on the M6 engine harness, what do i do here? Were does this wire normally run to on a A4 car? Im pretty lost on this one.

E. "Starter Relay Coil Supply Voltage" - 1 of the 2 Thick wires on the plug, so im assuming it handles some voltage. Does this connect directly to the starter? or perhaps a relay?

F. "Clutch Start Switch Signal"- the other 1 of 2 thick wires on the plug. This one is rather confusing due to the plug, and pinout, being for a A4 car. Why does the Auto car have a Clutch start switch/What is it? Is it the same 2 pin connector clutch switch as the M6? if thats the case do i do the same as mentioned about the NSS and run the signal wire to this wire and then just ground out/leave alone the ground for the original CSS?

[sweetbmxrider]

A - Should be good with just a ground here

B - Connector 1 Pin 34 of PCM, should be an orange/black wire coming out of it. This needs to connect to Pin B as it effects Idle Air control and can set a DTC for VSS. Technically this wire handles other **** but we can deal with it later if you actually give a ****. (Hatch release and Brake Shift Interlock - both can be bypassed)

C - Can't find the circuit yet but its from C220 which has the Orange/Black wire as well. Probably somewhere near the dash/firewall area. Link (https://ls1tech.com/forums/conversions-hybrids/437572-few-connector-220-230-questions.html) showing other headaches for you. Found Instrument Panel fuse block fuse 2 TURN B/U Brown wire feeds terminal C

D - Instrument Panel fuse block fuse 2 TURN B/U Brown wire feeds terminal C and terminal D goes to the reverse lights through connector 400. C powers D my man.

E - Underhood fuse block 2 STRTR mini fuse 15amp has the purple/white coming out. The clutch safety switch has the purple/white wire which feeds terminal E and....

F - the Dark Green wire is the other one which feeds the Starter Relay coil side I believe. Other wire is Yellow/Black on the relay which should be for VATS ground signal from BCM which I assume you can ground as well as some other rewiring if you want to bypass vats. Found the last diagram I needed so some of the pieces didn't fall in till the end. Let me know if you need clarification etc :lol:

A- Just grounded, easy enough.

B- The C220 connector has 2 blk/org wires. 1 of which is for the NSS(Pin H) according to posted Pin out. Pin 34 on the blue PCM connector is the noted as a blk/org wire for the NSS as well. Im going to assume that wire goes from Pin 34 on the PCM directly to pin H on C220. So i will snip wrie and fix new wire to the blk/org from pin B of the shifter plug, yes ?

C-The second blk/org wire out of the C220 is pin F. This is labeled as "UART Serial Data" on the pin out sheet. I dont know what this means. Do i run pin C of the shifter plug to pin F of the C220? Or do i run it directly to the brown wire off fuse 2 of the interior fuse block "TURN B/U" which im assuming is Turn signal and Back up lamp

D- brown wire off "TURN B/U" feeds pin C and pin D goes to reverse lights threw connector 400. What is connector 400? and C powers D? Does the wire that runs into pin C also provide power to pin D? so when the shifter goes to the reverse position, it completes the circuit and signal is sent to the "turn B/u" fuse? Do i just run a wire from pin C to the brown wire?

E- Run this wire to the purple/white wire coming off the "STRTR" 15 am fuse on the fuse block under the hood? or can i just connect it to the purple/white wire by the pedals for the M6 NSS?

F-This one confused me a ton as well. "you can ground as well as some other wiring" So do i run this to a chassis ground? the C220 connector has a grey wire off it for the CCP singal. Which im assuming is the same grey wire that goes into the 2 pin connector for the M6 Clutch switch. Do i just run the wire for pin F to the existing grey wire for the Clutch switch?






DISCLAIMER: all of the above may be in correct. I am no expert at wiring, but it made sense to me.


DISCLAIMER 2: I am not an artist, im sorry for my poor drawings. But here they are. 2 versions. both pretty much the same.

[sweetbmxrider]

A - 8-)

B - Don't snip, T into this one. It hooks into the hatch release and brake interlock etc. But ya, sounds like you got this one.

C - Brown wire from the fuse labeled TURN B/U (Back Up) feeds pin C. Hook C up to the fuse, not the other wire.

D - Run the Light Green wire from the shifter to the reverse lights Light Green wire. Connector C400 is a 6 pin connector near the driver rear tail light. It feeds the rear lighting. Obviously the reverse light wire is here. You can probably trace it back a bit in the car and tap into it. Got it?

E - Yeah, you can just connect it to the CSS wire.

F - Sorry I was tailing off on the idea of deleting VATS. Ignore all that and the color is Dark Green, its the other wire on the CSS. Yes, connect that wire to the shifter wire.

We good or want some ms paint brah???

A- Gunna ground

B. T into in on the engine harness side by the PCM? Or am I okay tapping into it on the Dash harness side coming out of the C220

C. Hook to fuse itself, not the wire comin off the fuse

D. run this wire to the back off the car and Find the reverse light wire. Do I T into it? Or just snip and connect

E. Got it

F. I think now you a tuner can delete VATS. Also I read it's pretty easy to bypass via resistor. So just run this wire to the grey Clutch wire by the pedals.




Right ?



Adam, thank you so much for your help. I owe you some shore point bbq blueberry ribs

[sweetbmxrider]

A - bukbuk

B - Wherever you want, just T a bisch

C - :facepalm: The fuggin wire, I didn't literally mean the fuse :lol: Its brown!

D - Snip it. I was saying you might be able to trace it back towards the front of the car. Don't know where it runs exactly. Up to you but the power is coming from the shifter, so SNIP IT!!!!

E - Blueberry ribs :drool:

F - Many ways around vats but part of it is pcm tuning, yes. The other part, you can do resistor or do it my way, up to you :lol: The wire should be dark green, next to the purple/white wire of the clutch safety switch. Don't know where you are seeing gray?

Iirc, the Clutch safety switch on the T56 has the blk/wht & grey wires. The NSS has the grn & purp/wht.

Did you mean NSS but said CSS? Or am I wrong

[sweetbmxrider]

Its technically called the Clutch Pedal Position switch and its Purple/White in and Dark Green out. Same colors are used for an automatic's Neutral Safety Switch. You might be looking at the clutch release switch? Or something like that, where it senses the clutch pedal is up, like a brake light switch. Orrrr something completely different!

At this point I'm 90% sure the only reason he is going this far into it, is to try to get one of his friends to get him on street outlaws. Which I'm going to guess is going to be off air by the time it's ready to go

[LS1ow]

Upon further inspection, Pin H is the signal for the M6 Reverse lights. Which goes from C200 all the way to the back of the car.

Since the A4 reverse lamps are run off the Body harness and not the engine harness like the M6 is, i should be able to snip and cap the signal wire from pin H of C200 were it goes into C400 at at the taillight plug, and just connect pin D from my shifter plug to taillight plug?

[sweetbmxrider]

Yeah, you can cap and connect wherever you want. Just want your power wire from shifter connecting to the feed wire for reverse light. Don't overthink it bruh!

[LS1ow]

Problem number 2:

Pin H on my C220 is Green, not orange/black. Judging by the pin out, stick cars use pin H as the reverse light(green) Auto cars use it as the NSS(Orange/blk)

Just ignore the colors and cut the green and run it to pin B of the shifter switch ?

[sweetbmxrider]

Sounds like it should work

When wiring pin D for the reverse lights, I noticed there is a ORN/BLK wire on the connector at the rear for the lighting. Assuming that's for the hatch release.

It feeds a relay so you can only pop the hatch when in park/neutral.

So run the green wire of pin H on the C220 to pin B of the shifter switch and call it a day?

Also, pin on hatch is something ive been debating, so well see were this goes

In my 3rd gen I put the hatch wire over to the parking brake switch so the hatch should only open when the parking brake is in the up position

Yup, when it doesn't work we'll discuss pin on hatch :lol:

Parking brake met its demise a while ago and is currently in a NJ recycling plant

Oh wait, you went TO an auto, just hook it to the PRND switch

All wiring is done with exception of pin A, the ground, that will do when the shifter is mounted and ready.

Was able to tuck most of the wiring into the factory loom so it doesnt look like a hack job.
