Hey guys, I had to replace my electric fan today, and I need a wiring diagram so that I can continue troubleshooting. I have looked everywhere on here and the web, but I am coming up empty. The original fan was completely locked up, so I'm sure that the fuse or fusable link is toast as well. The red and black wire leaving the fan go into a much larger loom back into the engine compartment, so I would like to know what wires I am looking for without tearing everything out. I need to know where the fuse may be, relay, etc. Also, does the fan turn on whenever the A/C is on, or just when the high pressure switch tells it to? And, what part of the engine (sender, etc) turns it on for additional cooling? Any help is appreciated. Thanks guys.BTW, this is a 7.4 MFI
