I have a harness for a lt1/t56 swap into a thirdgen. It has a fuse box, all wires and plugs are labeled. Plug any play. I'd like to get $200 obo out of it.

great price......

If I didn't just sell my swapped car, I'd snag it

 

How does this plug in? I have a 92 I'm swapping an lt1/t56 into. Is this just from the main connector to the engine/trans? Any special instructions involved?
I don't recognize the black box on the bottom left. Fuse box? So this replaces the entire wiring harness under the hood including the stock fusebox?

Lol lot of questions, but I'm def interested.

 

It plugs into the firewall right at The brake booster. This harness replaces the entire engine harness. The harness is plug and play. Plug in everything, hook up the battery and everything should work including the gauges. The fuse box you see in the picture is for the things that your old motor doesn't have. Let me know if your interested.

 

Kick ***, sounds great, my last question would be does the car run with the stock pcm, or would I have to re-program it?

Thanks for your help

 

Uses the stock lt1 PCM. Just plugs into the harness. You will need to have your computer reflashed if you start modding though.

 

Final question. Does it matter what year lt1 / t56 I get to use this harness? I was under the impression that the optispark unit had different connectors from 1992-1994 and 1995-1997 LT1s.

I also need to know if this is odb1 or 2.

Thanks

 

It works on any lt1. I'm guessing it's ob2?

 

Well here takes a look at this, it shows the differences between the years.

The two different optispark connectors


PM pocket, and see what interface it is, obd1 or obd2. I need to know.
Thanks

 

I'm 99.9% sure it has both.

 

Sold!!!!!!
