Disagreeing Fan Connectors

[brandone.lance]

Hi all!

I bought a replacement radiator fan for my 2002 4.0L Grand Cherokee. It has a three pole male connector whereas the original had a two pole male connector, which connects to a two pole female connector into the wiring harness. It looks like they both have one ground cable, but they differ in the number of positive cables.

If these are both two speed fans made for the Grand Cherokee, they should draw the same current for the low speed, and the same current for the high speed. They both use only one ground wire, which appears to be the same gauge.

Would it be completely wrong to splice the plug from the old fan onto the new fans wiring?

Thanks!

It looks like they sold you the wrong fan, can you take it back? Your fan is electric and not belt driven? What your doing will probably work,but, why not take it back and get the correct fan? My wiring info shows dark green is voltage, the other, white with black tracer is ground.

Yes, it's electric.

I bought it online... but I will check into their return policies. It fit like a glove into the shroud when I installed it, so I wonder if it is for a different year WJ?

My original had a single blue voltage, and a single black ground. The new fan has two green voltage and single black ground.

Any idea on whether this will pull too much current through the relay? That's the whole reason I'm changing the fan, is because I'm on relay #4 after the original fan started to show it's age and got power hungry.

I don't think I have the wiring diagrams...
