87 cluster vs 91 cluster
 

hey guys as many of u know i did a swap from 87 irocz to a 91 rs v8...will the 91 cluster work with 87 wiring and set up even tho it reads 110 on the speed and the 87 read 145

IIRC the 91 is an electric speedo and the 87 is cable driven.

nope the 91 cluster will not work.

on my 86 bird, i used a 91 cluster and the 86 had a 85mph speedo and the 91 had a 120 mph speedo and it swapped riteout and the speedo works as it should but thats a bird, idk about Camaros.

Thanks guys I did some fab. and got my old dash to fit in there and my cluster so im all good now thanks alot lot. The cars not far from being on the road I would say sunday it will be all put together.. Thanks again...

So, you were able to put the '91 cluster in an '87?

no the 87 went into a 91...

Did you swap the whole dash, or did you just ghetto-fab the old cluster into the 91 dash?

I'm trying to do the opposite (electronic into an '89).

nah i put the 87 dash in to

That's cool.

If possible I want to use a '91-'92 style dash, but keep the '89 cluster to avoid the hassle of the electonic cluster.

Picked up a '91 dash yesterday. Removed my '89 dash today.

im putting a 89 dash in my 85 which is all getting swapped into the 89 body

Ummmmm wasn't the 89 dash electronic, or are you talking digital? I know mine was. Pretty sure the 91-92 dash is unique though

91-92 camaros were electronic
86-92 birds were electronic

Yes, the '91-'92 Camaro dash is unique and different from the '89 Camaro. My '89 has the cable speedometer. I like the updated style of the '91-'92 dash, but I have to sort out the electronic speedometer.

you need a buffer box out of a 86-90 bird, it a yellow box with a bunch of wires and then you need the VSS. dont bother looking for a buffer box in a 91-92, they are incorporated inside the ecms on those.

I have an 89 buffer box if you want it, car is about to get junked so speak now.

This is behind the gauges or under the dash in the Firebirds? The local yard has several Firebirds so hopefully I can locate one.

its been a while, i know its under the dash, not sure which side, its about 3x4".

Yup, and bright yellow. about 1/2" to 3/4" tall. just a small circuit board inside.

There is a yellow box on this '90-'92 Camaro dash that I picked up @ the junk yard. Not sure what it is for. It's on the driver's side. :shrug:

i'm gonna say thats for the airbag. 90-92 were speed density TPI systems that ran off the 730 ecm, the 3.1v6 also used the 730 just with a different chip. those car had the buffer in the 730, so i am almost positive the didnt have the part u need.

The sensor is under the lower dash panel on the passenger side, right near the PCM
