Harness through metal Question
Since I listened to internet people, I need to cut a access hole to allow the trans plug to fit here.
This is from under the car, the connector needs to be able to have a harness plug into it. http://i924.photobucket.com/albums/a...g?t=1361837459 So, my idea is to cut a square out from the inside, see dashed lines below http://i924.photobucket.com/albums/a...g?t=1363045503 Then weld a plate over the inside with a grommet riveted to it, similar to below http://ls1tech.com/forums/attachment...le-grommet.jpg Thoughts? I am not a welding/body etc kinda persons so wanna get some opinions before I cut away. The hole was from a pilot drill, was gonna try a hole saw, but that was not a good plan. Measured out decent though, found it first pilot hole/ |
why a square hole? and those seals don't require welding do they?

A square would be easy to cut, then mold a plate to the curve, weld it, and have a grommet bolted/riveted etc to the plate. |
You can cut a round hole with a dremel. either cutoff discs or maybe a spiral saw blade (I think they make those for metal)
is the underside flat or equally curved |

Both sides are curved, and I just was under the impression a piece of 1/8 steel molded over the square cut then welded down was less hack than attempting a circle cut. But, again, I am not a body guy |
how curved is that area? those grommets are pretty cool. id say cut it with a holesaw put the grommet in and just bang it into place and screw it in with the supplied holes. If its not going to be seen you can squirt a little seam seal around it to ensure its air tight... the ring around the seal is metal right?

look on your driver side seat area, trans tunnel, thats the area in question |
is is just a harness or do you have to clearance for the connector too? i know it is a tight fit

lol i know thats where it is but its hard to tell in pic how curved it is. i dont see why you can just cut a nice hole with a hole saw and use those grommets. if that ring is metal you can bang it into any shape you want so curved area shouldnt really matter to much. only thing is you will have either rivits or screws showing under the car in the tunnel. if you can live with that i think it would work. another thing to think about is if you have to pass a connector through it you may want to cut your holes and everything and maybe cut the wires and just pass the thin wires through the grommet connect it into the trans and then solder the wires inside the car. otherwise your gonna have a bigger hole cut inthe rubber grommet and its not gonna be air/water tight

if you wanna cut and weld a plate or somthing that is doable to. i can help ya with that if you want to go that route. but your car is at your house and not drivable. assuming you dont have a welder and prob dont have same plug for 220 i have on mine. so i dont know how we could make that happen unless you tow it here

I just do not think a hole saw is gonna be a clean way of doing it, just imagining it grabbing and what not |
I'm assuming the problem here is the unibody structure that is seen in the first pic.

Thats kinda what i had in mind, then weld a plate on the inside, goop up the outside with a plate to seal out debris |
More hack than a hole saw imo.
|
Why not just cut the hole, make a plate up and silicone it on with some self tapping screws since u dont have a welder.

Do you have an air compressor? I bought a Carbide Burr set from the Snap-on guy and they work great. Something like that may be easier to work with in that area.
|
Have you looked to see if anyone does or can make a custom connector? like 90°, then you can run the harness back a little . not a simple mod but shouldn't be impossible. only like 12 pins or something like that right?

Would def use that option if I could, believe the truck connectors are right angles but again, its too tight. |
saw this earlier, thought of you

I was thinking he would just punch a hole through the tunnel.
|
That is neat!

was thinking more about this... is there an actual clearance issue on the trans half of the connector or just a clearance issue when the harness end is plugged in? was thinking today to do it (imo) really clean would be hole saw what you need in that unibody frame brace to clear the connector then from inside the car get a smaller rubber grommet and cut a hole in the actual tunnel itself to what ever size the grommet is poke a small hole in the grommet and depin the harness and punch the wires through the hole made in the grommet (this will now be pretty tight fit for air/water) and repin the connector. loom the portion of the wire that is on the outside of the tunnel for any sharp metal made by the holesaw. to me this is a clean way of doin it with minimal work. tell me what you think. dont forget to etch prime and paint any bare metal.
