I have completed my rebuild for the most part but ran into an issue with the harness near the ecu. I can't figure out where a couple of wires and connectors terminate.
There are two black connectors by the ecu at the end of the harness that I don't know where they go. One goes to the fan mod switch and I'm not sure where there other plugs in. They look like grounds. There is a black, white/blue, black/white, and black/red in the harness.
There are two spade terminal looking looking ones too. One is black/red and the other is black/white.
A lot of the confusion there is from the fan recall harness. Do a search on that - I typically remove the fan recall stuff. An FD that is running proper fan temperatures has no need for it.
That said, the one wire plug with the black connector on the end is the test connector for the fan recall, it stays unplugged. The wire with the ground loop on the end just needs to be bolted to the car, typically to one of the ECU mounting bolts. The multi wire black connector plugs into the "brain box" for the fan recall, it's a small black plastic computer.

Thanks Dale, I found that info this morning. My new engine harness had the fan mod built in and my 93 had the patch harness. I'm all good now!
