JK Radiator Fan Replacement (Universal)
Hey Matt I just emailed him asking about your fan model, I'll let you know soon as he gets back to me.
I am ordering SPALUSA part # 30102049, I will be putting a kill switch with it also, he said it was best because when fan is half submerged in water it could cause bend or breakage of fan blades. I will only shut it off if stuck in water that deep not just to go through water/mud. He sent me a diagram of how to wire the relays. He said to use one 40 amp single pole double throw relay if wiring without switch, and two if wiring with kill switch.

There are 3 wires at top of the fan shroud electrical connector, black is ground and the other 2 are high and lower speed power.

Have we found out if the "green" resistor will affect the SPAL fan install?
I installed mine this weekend. Pretty much an easy install. The only thing I have noticed is that the fan only runs when the Jeep tells it to run HIGH. I know the OEM motor is a two stage motor but my guess is the SPAL motor is only a one stage. I will post some pictures of the install sometime tonight. I did mine a little different but I think it will work better.

Dont know. WHen I installed my SPAL fan, I used all the stock wiring to make sure to keep the green thing in the loop, but it doesnt seem to be doing much...
need a schematic to determine what's upstream and controlling the fan.
