I swapped a '91 interior into my '85 which involved swapping in a '90/'91 engine harness. My '85 was originally MAF and now the '90 harness/ECU is setup for a MAP system.

The 90 harness/ECU takes care of all wiring issues. What I know needs to be done is:

Connect MAP sensor/run vacuum line

Install Air Intake Temp sensor

Change out knock sensor (shows a different part # for '90/'91s)

Am I missing anything else anyone can think of that's part of the MAP setup? Anyone know of a link discussing the MAF/MAP swap anywhere?

thanks,

My dad was installing a 91 engine in a 89 and I know he had to change the knock sensor to a 89 and plug the MAP. Sounds like you are on the right track. Sorry, don't know of a link.
