i swapped a 91 na into an 88 and was wondering if i could use the 91 ecu in the 88 with out swapping harnesses....

 

The short answer is no. The plugs aren't the same shape, and the wires are in all different locations.

The long answer is yes, but only if you cut the plugs off and re-arrange all of the wires. But you're better off using all S4 electronics on the S5 engine, so you can leave the wiring alone.

 

thats what i thought but i had to ask... Thank you you have been alot of help.
