im trying to put a 91 gt wiring harness into my 87 lx. is there any problems i will have? i think the plugs in the vaccum blocks just outside the firewall where the harness comes threw are different. are any other plugs different, and last what is the pluggin just up wire from the alternator?


thx for your help

From a post by bbunt302...

Just for reference, here's a list of all the compatible years:

89 harness should work for 86-89 as long as you're using mass air.
90 harness will only work in a 90. (B/c of air bags and dual dash connectors)
91 through early 92 harnesses should be compatible (single dash connector, fuel pump relay under driver's seat)
Late 92 through 93 harnesses should be compatible (single dash connector, fuel pump relay under the hood)
