For the left side (drivers side) of the wiring harness... would a harness GTU-S from 1990 be able to replace a '88 n/a GTU? Same basic features. Basically the insulated wire running from my ecu to the crank angle sensor got drilled though, which hit a few other wires too. Somehow I need to resolve the problem and I was hoping to replace the whole harness.

Suggestions?

 

i dont think so the plugs that go into the ecu are different on the s4, s5 models. I would stick with s4 stuff if thats what you have. Makes it alot more plug and play.

 

nope wrong series... not compatible.

 

ok, how about a '88 gxl?

 

an 88 GXL harness would be compatible with a 88 GTU (and the same harness actually).
