    Question A/C Condenser Fan wiring diagram

    Hello,

    I'm trying to help my A/C cooling efficiency on my 94 sub by installing a A/C Condenser Fan Assembly. My rig didn't come with either an auxiliary electric fan or a condenser fan but it seems it was an option.

    The unit i purchased bolted right up to the factory holes but I can seem to find figure out the wiring. I have an "extra" plug in the general area but the plug doesn't match the fan plug. The wires on the truck plug are green and black? I would like the fan to turn on when the A/C system is on..I was told by an A/C mechanic that this would help cool things down while in traffic.

    If this fan were an option, wouldn't the wires / relay be in there somewhere.. thoughts?
    thanks...

    Can you check the plug in question with a volt meter? Check with ac off, then with it on. If you get voltage with it on wire it up! you can get your own connectors if you want.
