Ok, I've been searching and couldn't find any info.

Well I have a 1987 Supra NA. I know that the ECU HAS to be the same as the chassis of the car due to the dash harness. But I was wondering is the engine wire harness also strict and has to be the same? Or can I pull any pre-89 wire harness?

I am also looking to buy a 87 wire harness for my NA-T conversion…

Any help would be grateful!

The engine harness part number is on the wires between the ecu and firewall. I thought all engine harnesses for 90 turbos were the same...I was wrong. Just match the part numbers.

Any pre-89 harnesses should be interchangable provided you match up N/A or Turbo, and Auto or 5-speed.
So i'd be ok if I went with a 88 Wire Harness? I got a 87 Chassis and 87 Turbo ECU.
