Here are the Part Numbers for the GM PWM Module Connector [Archive]

All,

Over the past several weeks, I have been conversing with Scott from TTI to obtain the part numbers for the GM PWM Fan Module connector. Scott at TTI was very helpful and was able to track down most of the part numbers with very little trouble. The small PWM signal terminal was hard to find and luckily for me, Andrew B used his local GM resource to track down this terminal. We are still in the process of prototyping a few of the small terminals to find the best one of the bunch. So...I have not fully tested all of these part numbers, but will share my experience when I get everything together. Most, if not all, of these parts are available in single piece quantities through Mouser. I believe that information like this should be free to the public.

Apologies for my impatience, were you able narrow the selection for the small terminal at all?

571-2-964286-1 (that is the Mouser PN, the TE Connectivity PN is 2-964286-1) is by far the best terminal to use for the PWM signal wire.

Thanks for the confirmation Andrew.

I went to the Mouser website to buy quantities of each but for all the parts (except the last small terminal) it says:

Shipping Restrictions:
Mouser does not presently sell this product in your region.

What's up with that?

Looks like I need to search for alternative places to buy.

Thanks again!

I bought all the parts from Mouser, did you guys have to modify the plug in any way to use it with the controller? Mine will not physically fit in without grinding off two small tabs on the outside of the oval that goes into the controller.
Thanks

Yes. You have to take a blade and open one of the keying cavities. Just look at it and you'll get it. It's simple.

Just to update this thread, I like 571-2-964286-1 for the small terminal. I guess I said that before, but just so we are clear :-)

Andrew

It's easier than that...take a small needle nose pliers and twist the plastic pin out of the PWM controller. Comes out in 1.65 seconds with a simple twist. No need to modify the connector

Any new updates on the small terminal? It look like Andrew's choice is sold in large quantities only. I don't think I need 99 extra of these just laying around forever. Just wondering if any of the other numbers work.

Mark,

I sure picked a fancy terminal...LOL...The truth is that the other part numbers will work just fine. Anything that starts with a 478 means that it is a Kostel part, which is probably more compatible with the connector. The TE Connectivity terminals I found by some accident and I felt it was "better." Whatever that means...

I'm planning a sniper install and would like to control my dual SPAL fans with the C6PWM and the Holley I/O. Looking at these part numbers,
Body (Qty 1)
478-9440101

Mouser says this part is not available. Has anyone else found this part elsewhere? My googlefu is failing me today.

Thanks.

I found this harness and it led me to believe it would. Perhaps I should ask on the Holley forum?

upon further review it looks like I'm wrong. I'll need to use that output to control a Derale PWM controller.
Unless I step up to a Terminator

The product description. Says nothing about being able to program the outputs how you want. I would consult the Sniper tuning manual.

I found a decent deal on ebay for that kit for $130 looks NIB. Has anyone figured out the connector for the other end of that harness? I guess I just use a Metripac or similar if I can't find the compatible end.

Steve,

As far as I can tell, that is a Yazaki connector. I haven't had much luck finding a source for them. I think the Spal catalog shows some part numbers for them. The junk yard has these, but obviously not the new terminals.

If I'm reading that correctly then yes, "SPAL p/n 30130628" should be a complete male connector kit including terminals and seals?

Hey Andrew, I plan on running two of these GM PWM controllers (1 for each fan) and driving them with m Holley HP...do you see a problem 2 different controllers with the HP? I tried one for both and it lasted about 50hrs.

There is no issue running two controllers off a single PWM- output (just split the signal wire) from the HP. If you want to get fancy, you can have a separate PWM- output for each fan and control them under different conditions. This of course burns up a valuable output.

Get yours while they last. 4 left after I got mine. LOL

I'm running the dual SPAL fans, my calc shows about 20 Amps max per fan, So I think I'm fine on one controller. Andrew, do you concur?

Hard to say! The stock C6 fan is 400watt...so 32 amps at 12v. Two at 20amps might be pushing it, but I have no direct experience with dual fans. I just know you can split the PWM signal from the Holley.

I did run across this the other day:
https://www.rockauto.com/en/moreinfo.php?pk=7096964&cc=1434490&jsn=447

Made for Ford Edge with dual fans. Don't know much about it, but I suspect it works just like the C6 fan controller.

I might just run one fan on the PWM and see how the car does. Then use the second fan as and all or nothing on a hard relay.

Looks great Steve. I read somewhere that this connector is part of the USCAR standard, which is why I have seen them on various vehicles and why it is relatively inexpensive.

Andrew

So I found a website that has the connector parts available. They're in HongKong and the website was a little clunky, but I'll keep my fingers crossed.

Guys,

Another option is to find a junk yard 2008 Ford Fusion. You can actually buy a Fusion fan AND controller, with harness for less than $200. The fans are big and would work great on old muscle car radiators. Then use the Spal Yazaki connector kit listed above for the mating side.

If this was available when I was building the Cougar, this is what I would choose.

They are a PWM controller, designed for EFI applications where the ECU controls the fan speed.

Otherwise just use a temp switch to power a relay when the fans are needed (IE no speed control, just on or off).

Thanks but what I am asking is if the PWM controller is stand alone with only needing a temp sender or does it need a PWM signal?

Don

eville

02-06-2019, 10:34 AM

What sort of input signals does that fan controller need? A PWM signal or just a temp sender?

Thanks,
Don

Don it needs a PWM signal. For your reading pleasure...

As was said above. It's literally the same controller at the C6 Corvette controller. So it needs a PWM- signal.

You ever have one of those, "crap, I didn't even think about that!" moments?

What's the difference between - and + PWM signals? Asking for a friend with a Spal fan and a Holley Dominator.

andrewb70

02-07-2019, 06:25 AM

PWM- pulses to ground. PWM+ pulses to positive.

What happens if you send it - and it wants +? System in question is functioning, can't remember what I set it to, do not have laptop to look.

The magic pixies get out....;-)

It's hard to set the wrong config because on the pin map you can't configure the same pin as PWM- or PMW+. That's a hardware limitation.
