[countrybull]

I am doing a 4cyl to v8 swap the 4 cyl is a 89lx coupe with a aod i have a 91gt 5spd donor car do i have to swap the harness that coming thru the firewall on the pass and driverside of the 4cyl car from the gt? or can i plug the computer in and do plug and play?

use everything from the gt. there were differences between 89 and 91 that will be problematic if you dont.

You will need the wiring from the 91 including the use of the complete dash and the steering wheel (the whole shaft also) or find a 1988 cali mass air computer harness or a 1989 mass air harness
