Got a f22b into my 92 that had a f22a originally.

Runs real solid. I did not do anything to the electrical side. The PCM is original and so is all the wiring in the harness.

Went to start it the first time and noticed there was no fuel pressure. The fuel pump was powered by a wire that was just laying under the back seat. . . . Hmmmmm

The fans don't kick on at all. I checked for voltage at the relay and it has power from what I can tell. I jumped the relay and the passenger's side fan turned on.

The temp gauge work just fine and there is no check engine light.

I thought about going to a aftermarket fan rheostat and a relay to hot while on for the fuel pump. But, I think it would be better to have it setup stock like better.

 

I'd get a Helms manual...either electronic or paper copy so you can check the wiring diagrams.
