You need to make a connector that combines the 4 fan wires into 2. Then you can splice your controller harness and put a 2 wire connector wire. But you need to make the 4 fan wires into 2 wires.

If you do not want to touch your existing harness (just in case you want to put factory fan back in) you can maybe buy an old harness and cut that one up which is what I did. I think they may even sell the harness now. Before had to buy a junkyard one or get one off an old fan motor if you did not want to cut yours up.

You just plug them in. DeWitts customizes the fans to have matching GM plugs

Just as an aside, I could not be happier with the Dewitt’s fans (and radiator) that I have. Make sure to report back!

I haven't mounted it yet, but I recently bought a DeWitt's radiator and Spal combo. The Spal fans are wired into a common plug, with two wires coming out. It is my understanding that I will have to splice the two wires into the OEM wires that plug into the fan module. I haven't found a pigtail that will make it plug and play, yet.

Hold the phone, those pictures are the SP015 for a C5.

The C6 uses SP463. This one does require cutting and splicing in the new plug.

Tom, I think you are correct and if those are 12 inch fans that is nice but they wont fit the C6 which needs 11 inch fans.
