I've run 2 fans with single PWM C6 fan controller (have to look at total power demands and keep in limits of fan controller) and know that works.

Lou is trying dual PWM modules controlled by single PWM output from ECM -will know soon the success of that route.

OK, that's good to know. I'm using the C&R Racing setup with their dual Spal 11" fans.

Is that the fan setup you know works?

Corvette fan is 400W - so at 12.5 V, that's 32 A. So long as your 2 Spal fans are below that current level, should work fine.

Anyone have a PN & source for the connector terminals?

A quick check of the dual 11" Spal fans shows current draw less than 32A.

Looks like I'm golden!

Thanks all!

x2, and looking for cavity plugs too. I've heard reference to "micro 64 connectors".

I have found this site.

http://www.obd2allinone.com/sc/details.asp?item=m5j3

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:

http://www.amazon.com/ACDelco-15-808...rol+Module+Kit

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.
