Like the title says I want to put a 87 body on my 85. I have read several different post but havnt found a definite answer on whether or not the wiring harnesses are the same. I'm not as worried about the body mounts being the same just the harness. Thanks

 

If they are both manual trans or auto trans, maybe. I don't know if the turbo has different wiring, I do know the computers are.different. I put an '88 body on my '85 4Runner but we changed the entire harness and gauge cluster as well as the steering column. It made it easier since the donor truck was a V6 auto and mine was a 22're 5 speed.

 

The harnesses will be different not very much different then doing any other type of swap.

Without sitting down and looking at both EWD`s it may be only a few wires need to be repined.

Then it could be more involved.things like the main body connecters might be different

It will not be just plug and play

You could swap all the wiring out of your old cab

 

The bodies are the same and will swap fine. The harness will not. Pretty much all connectors and sensors will be different from the 85 to the 87. Especially since its a turbo.

Just swap out the harness for your '85 and you'll be fine. It really Isn't hard to do. I've swapped multiple harnesses in both trucks and runners, just take your time.
