Default AFM/NPP Pigtails

Hello all, not your typical AFM post.... LOL. I seem to have broken a connector on one of my NPP valves and it appears the clear rubber gasket is missing too. I need to splice in a new pigtail. Does anyone have the actual pigtail part number and does anyone happen to know if the the rubber gasket is a separate part number? I have looked on the GM parts site and they list 106 different pigtails with not so great images and not a lot of detail. I appreciate any help. Why does it need to be so hard? LOL

If you want to try and find the connector, you can look here, https://www.corsa-technic.com/ they have a good assortment of connectors, search using their "by number of contacts" under connectors, if you do not find a match, they have been very responsive to me, if I send a good photo and use description they may have some on the shelf that are not in their catalog.

The AFM and NPP actuators use the same connector type but different color (most likely to help with Assembly Line quality).

If you want to spend a fortune for the pigtail, you can go here: https://findpigtails.com/connector/c...RoCgIcQAvD_BwE

Conversely, the connector body should have a part number on it. You can look for that online and buy just the connector at some place like Mouser. With a little bit of research...or if you just call Mouser....they can get you set up with all the individual pieces.

The connector description is: 5-Way F 1.2 MCON-LL Series, Sealed (BK)

Unfortunately GM doesn't list a service connector for the exhaust. They want you to replace the entire transmission harness that the exhaust plugs are part of....which is totally insane but it is what it is. You didn't say which side, so I just picked the left one. The right uses the exact same connector body.

More likely than not it's this one: https://www.mouser.com/ProductDetail...FW4V%2Fg%3D%3D

I put maybe 30 seconds into the search so you'll need to verify it. This is the body. It's not pinned / no pigtail. Probably doesn't have the seal. Like I mentioned above...Just call Mouser.

Using Jim's info above and about an hour of lookups and cross reference.... For anyone in a similar situation, these are the exact same connector used on Audi's MAF sensors and other parts. The best part, and highly unusual for Audi vs Chevy, there are plenty of sources for the connector already pinned and pigtailed. I am posting an Amazon reference, but there are many more out there. Thanks again for the initial info Jim!
