PWM cooling fan(s) control using ECM

I have found this site.

Looks like you can pick up the connectors there. 10 / $2.95.

Forgot I had a document with some information in it. Like GM PNs for the pins, don't know if it will help finding them or not.

Here is where I bought my PWM modules:

You can't open them without damaging them but I was curious to know how the insides of the Corvette version compared to some pics of similar MB units I saw on the net. Here is what the Corvette version looks like inside. They are different than the MB units that look the same on the outside. The MB units do look like they use the same connector as the Corvette units but they will not sell them separately either. I gave up on finding a connector. We are attaching the wires individually with appropriately size female spade connectors.

Thanks Lou! I just ordered the last one in stock.

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.

Here is another site to get the terminals from:

Downside is you have to have a $25 minimum order.

mouser.com also has the ecm terminals. A lot of sites call them Delphi connectors but they are really molex. The molex pn is 33467-0005 minimum quantity 1.

Excellent! Can you find the cavity plugs? I just spent 5 minutes on Mouser without any luck...
