That's it. I said u-bolt, but I meant u-nut.

Ah, U-nut, I never knew what these things were called.

Scot,

Someone on another forum posted that there are supposed to be some sort of rubber grommets that go into those square holes in the fan shroud. Let's see if we can track those down.

I'll find out. Probably something like this is my guess:

The ones with the metal inserts look about right. Where do you find those?

Andrew

I Google-ed "rubber damper insert". I think an ACE hardware store near me has them. Not sure they have the metal insert.

I have 5 complete sets. When the seals get here I will also have ECM terminals. If you have the GMPP controller kit & want to add the Maxi fuse/breaker in the fuse box to power the fan, I can get the terminal for that fusebox as well.

I spent a ton of time trying to find this connector. If you have searched it you know they aren't available from GM.

When the seals get here I will have everything needed (except the wire) to add this fan module. $50 shipped to anywhere in the US.

Wire seals finally showed up.

Now I have everything.

I've just finished wiring my customer's fans. I split the PWM signal (blue wire in, 2 green wires out) at the MetriPack 280 connector, and grounded the controllers to the radiator core support (just below the connector). The fan power and ground signals go down and connect to the fans below.

I just registered after reading this entire thread.

I'm trying to figure out how to wire up a SPAL brushless fan using the factory C6 PWM controller.

Essentially I just want to replace the OEM fan with a more efficient brushless fan and use the PWM controller and ECU to control it.

The new fan has a PWM controller input, but I'm not sure if I can wire it directly to the PWM wire on the fan controller.
