I remember trying to find this connector before, seems like it has 4 big terminals & 1 small one, or is there small ones? Is it sealed like a weatherpak connector?

Anyone know the GM part number of the PWM module? Maybe I can have some of my old Delphi co workers track down a connector.

The AC-Delco pn is 15-80803 if that means anything.

I talked with a local tech today who does a lot of late model upgrades. He said that on C6s they routinely swap to dual Spal fans and get another fan controller and split the signal line from the ECM with great results.

So it seems a single controller with dual fans and dual controllers splitting the signal both work fine.
