just kinda wondering....how hard do you think the wireing for a 87 n/a to 91 turbo j-spec motor would be? is it really that hard if i have the front clip? and the shop keeps saying after minor change....anyone knows what that means exactly?

 

You'd have to replace the entire wiring harness.

 

so all i have to do is change everything over? put the motor, tranny, ecu, wireing harness, drive shaft, diff, blah blah in?
