I only see 4 wires, on that plug there are two big and two small. How does that controll two fans? I would think the two small ones turn it on, and the two bing ones for the power (just like a normal relay)
Or is there a seperate one for each fan?
I apologize. We have 25-30 Chrysler vans in our fleet. I just checked wiring diagrams and these modules are wired to two fans in parallel so one relay controls both fans together. The reason it seemed like they control fans independently is because some vans have an additional control circuit for one fan based on A/C input.

The pictures I posted are from a site that had prices ranging from $30 to $50. Name starts with rockaut.
