Hey all, I am in the process of installing a electric fan, I have one question.

Where do you splice the wire for the A/C to turn on the high spped part of the fan. I have every thing wired except that one wire that controls the A/C

I think that I can splice it into the wiring harness under the fuse/relay box on the drivers side of the engine compartment , but not sure which wire, if you have a better idea let me know.

Thanks
Don
