I am doing the ever popular 4cyl to 5.0 swap and there have been numerous threads I have searched but none answered this question. I have a 86gt complete donor car that I am using for my swap. My question is will I have any issues using a 86 harness/computer with my 89? thanks for any help

I am working on splicing a 86 harness in my 84, it will not plug into your harness, so i will have to be spliced it looks much more simplier than the 90 harness i have, but we will see also the fuel pump wiring is all integerated into the harness. Just fyi I hope this helps
 
Kabuki I am mapping out the 86 harness and it seems more simple than my 89 not as many splices but if you get the correct year it should just be plug and play for you i have a post going about a 86 in my 84 on here and Foureyedpride.com so i will let you know how it goes
