Black Bear and Nelson Performance Nelson Performance both sell an add on fan harness. They can also turn the fan option on in your PCM

If you have the 34in radiator you can either buy the OEM style E-fans from Dorman through a parts store or on Ebay. There is also used ones that pop up from time to time.

Make sure you get the harness that adds 2 wires to the PCM, not 1 wire to the PCM and 1 wire to the A/C clutch.

Well they used to sell them. Since they changed the site around I can't find them any more.

Looks like Nelson still builds them.

They were the ones who built the blackbear harnesses, to my knowledge. I had one of them previously. Very good quality.
