Try your local wrecking yard. I'm pretty sure from 87 to 93 was the same engine harness for the fox. If you don't want to go that route, LMR, AM, JEGS sell new ones.

thanks for the info. I have the the fox body doner car. I may go that route. I would prefer a complete harness with everything under the hood and dash including brain box with labels? To plug into my coupe. I just got off the phone with LMR. I will try the others. So far every company I've called is telling me a universal harness kit and a harness kit w/EFI

If you have the donor car (complete harness) it's just a matter of swapping it over. But yes, universal harnesses is how most people go.

Many issues presented during the first few years of EEC-IV, '89 to '93. One was wiring coloring codes. If you have a solid background in Electric Theory, you can work around such things. I have transplanted many EFI engines, mainly EEC-IV equipped into various vehicles. One very rewarding was a '68 Mustang 351W, I used Ford Motorsports kit with 24# injectors, which was derived from the '93 Cobra, and it worked like a charm! imp
