Here are the Part Numbers for the GM PWM Module Connector
 

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.

Body (Qty 1)
478-9440101
$8.58

Large Terminal (Qty 4)
478-23124472620060
$3.45

Large Terminal Seal (Qty 4)
478-10800472742091
$0.77

Small Terminal Seal (Qty 1)
478-10800444522091
$0.10

Small terminal plug (Qty 1)
478-10800472631091
$0.12

Small Terminal (Qty 1)
We are Prototyping these Options - Stay tuned:
478-22124492060050
478-22140492060050
478-22140472970050
571-925595-2
571-2-964286-1

Thanks for the Info, I was also working with the local TTI branch but couldn't get them to quote me a 1pc qty. Although they did give me the plug for free, just need the terminals and seals now.
thanks again!

Not sure if you've been able to verify the small terminal connector but I was looking through the quote and they referenced a Tyco part number 968119-2 for the the female terminal and Tyco 967610-1 for the seal. looked through the PDF drawing and they seemed to be the right dimensions, but need to assemble to find out.

I'll order parts this week and let you know if it all works out.

Thanks for posting this. It wasn't easy to find a while back.

Tony,

For the small terminal I like the 571-2-964286-1. It is a very robust terminal with copper contacts and double retention clips. Looks like Mouser has these in stock now. I don't think 968119-2 is right. The small terminal needs to have sort of a puckered duckbill look to it. The 571-925595-2 is a less robust and less expensive version of 571-2-964286-1.

Andrew

I just ordered all these and enough to make two plugs and test which I like more for the small terminal. Only one of the above part numbers was back ordered above. I'll take some shots when they arrive and let you know my thoughts as well.

Thanks Andrew, spent some time on the phone with Mouser and he cross referenced a 571-968221-7 as a replacement for 968119-2 so i placed an order yesterday but considering that you've "been there and done that" i'll order the 571-2-964286-1 also and let you know of the differences.....

thx everyone for the help, really appreciate it.

I ordered the above parts and the PWM controller from the link below:

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

When I tried to insert the empty shell into the PWM controller it didn't fully engage so the locking tabs would hold the shell into the PWM controller. Does anyone have a picture of the above parts fully engaged into the PWM controller?

I'll snap some photos when i get home.

There is a cavity in the connector that must be hollowed out so that the tab on the fan controller can mate with the connector.

Andrew

Got pics? I'll take a better look when i get home to be sure i'm looking at this the right way.

Thanks for the response.

William

William,

Once you look at the parts it will be obvious what needs to be done.

Andrew

I'm sure it will be, i got to look at them for about 2 minutes last night in the kitchen before rushing off to dinner. I'll look today and take some photos of the modifications.

Hey guys just a quick follow-up but I found a difference in the PWM module plug. I order 2ea of the P/N 478-9440101 and I still have the plug I got directly from ITT P/N 9440101, see the pics

There’s a restriction I circled in red that didn’t work with the PWM module, there’s a plastic piece protruding out in between the electrical connectors of the PWM module. There’s one on the other side also but there’s not a restriction on that side of the plug..See pic

If you guys have gotten this plug to work on your PWM module then maybe I got a different version off of ebay….?? By the way the small terminals ITT referenced in my quote didn’t work….as Andrew suggested earlier. Ordered the ones Andrew mentioned, should get them tomorrow.

should've mentioned for clarity the small red circles only identifies some differences it didn't affect how it fit.

thanks Andrew, should've read the post before posting my tirade of info....You're all over it.....thanks again.

FYI, the 478 prefix on that part number is just something that Mouser adds. It's the manufacturer code. I'm surprised that you got two different connectors with the same part number. Regardless, either will work. Don't forget to slide the release bar when inserting the terminals.

Andrew

Well i was "handed" the first part by hand from the ITT representative so technically I didn't order it but their quote stated 9440101, regardless like you said you can do some minor cutting and make to other work. BTW your suggestion for the small terminal 571-2-964286-1 worked great. thanks for all the help.
Tony

I just want to clarify the above picture, and hopefully it doesn't lead to further confusion, but here it goes.

The connector on the left is technically PN 9440102, however vendors such as Mouser list it as being the same as PN 9440101. The 478 prefix is added by Mouser and indicates the manufacturer, in this case Kostal.

Ideally, you would use PN 9440102, but PN 9440101 works as well, if the oval circled cavity is hollowed out.

This information is straight from the Kostal blueprint, which is accessible through Mouser.

Andrew

Thanks for clarifying guys. I was hoping to have ordered and received all of the parts and did a write-up on it, but I got sidetracked.

I went into the controller with a needle nose pliers and just twisted the plastic pin out. Connector fits without modification

Old66Tiger, Andrew, et al. I wanted to say thanks for sharing these part numbers. I can't tell you how many hours I spent scouring the internet for them before giving up (this was before this thread). I owe you guys a beer :happy23:

Thank Bob for the heavy lifting. I was the one that managed to track down the little terminal for the PWM signal cavity.

Andrew

I would like to add my thanks to those who are responsible for getting the part numbers for the necessary connectors for the PWM module.
FWIW, I was doing some perusing and ran across this:
http://www.rockauto.com/en/moreinfo....1432165&jsn=10
It is a PWM module with wiring harness from Rock Auto.

Thanks for posting that. Always good to have options. That other round connector is made by Yazaki I believe. It would be nice to find the part numbers and a source for other side...

Andrew
