shbox site is your friend on this one. you'll have to do some research and compare. the biggest connectors to pay attention to are the c100, c200 (210,220,230)

A 95 harness is the only one that will be an exact match. There are slight differences to 94 and 96-7.

Hey Rob can you elaborate on that? I am getting ready to repin a harness from a 94 for my 24x setup. As far as I knew they were the same.

The 1995 LT1 harness is unique however you can convert a 1994 if you can read a schematic and re-route and re-terminate a few of wires. I buaght a 1994 harness advertised as 1994 and 1995. I had rewire it, grafted in a C1o5 connector and ohmed it all out just fine.

The connectors, wire colors and pin-out is identicle at the PCM.

I wish I could remember all the details and help further but if you go to.shbox site and look through the electrical section you can find everything you need. Please support the site while you are there, it is operated on donations and it is a blessing for 1995 F-bodies (and some info for 1993/94 and 1996/97).

Good Luck

The engine harness connects at the P/S shock tower with connectors C100 and C105 and in the passanger compartment (under the dash behing the P/S trim panel) through connectors C210, C220, and C230 (the ac connects there also). Other than that the body and dash horness are indepenent of the PCM.

That's all I know.

As already suggested, use my site to check connector differences. That is why it is there (so I don't have to "elaborate" the same info all the time ).
