  1. Ahh, that makes sense! This is supposed to be from a Yukon SUV. I wonder why GM does that?
  2. Thanks, I'll try calling, as all the stuff I found on Google are on salvage reseller websites, and they contradict each other (some say it works on 08 GMC Sierra's; others say the part doesn't.)
  3. Thanks, but that's what I'm trying to say - the part doesn't exist on any GM part website, including GM Parts Direct. It has been superseded, so if I look up BCM part numbers today, it will show me the new ones, not all the old part numbers that once worked. I'm basically asking if a GM parts guy that has more access can look up the part number.
  4. Yes, I didn't want to program it yet before verifying because the ebay seller won't accept returns of BCMs once programmed.
  5. Hi all, I just bought a used BCM on eBay and the part that arrived is 20939138, which wasn't advertised on the listing. It's not coming up on any GM part website. Does anyone have access to look it up, and see what part number superseded it? Also, will it work for an 08 GMC Sierra 1500, once programmed? I'm trying to see if it will have full functionality, or if I should go through the hassle of returning it. Thanks!
  6. Thank you! Do you know how I would hook this up to a standard TRS 3.5mm jack?
  7. Does anyone know what the "audio common" wire is (see attached)? I understand the left and right channels, and ground appears to be just connected to the bare metal shield in the audio cable, so I don't think common = ground. Maybe it's a center channel? I'm basically trying to hook up the audio aux input in the center console of a 2018 Sierra to an aftermarket headunit. When I connect just left, right, and ground, I hear both channels, but it seems quieter and less has less bass than if I plugged directly into the aux port of the headunit. 2018 Connector.pdf 2018 Radio.pdf
  8. You could, but It would be a lot cheaper to buy an inverter from Harbor Freight, and wire it up yourself. You could buy the power outlet part and install it in your console to make it look factory, if you wanted.
  9. I'm grafting a 2014-18 40/20/40 jumpseat center console into a 2008 NNBS truck with existing 40/20/40 jumpseat center console. I was going to use the wire harness to hook up the USB, audio, and power ports, but after looking at the price, and since I would have to solder anyways, I'm just going to make my own cables and solder to the ports in the console.
  10. Thanks, but I'm looking for the 40/20/40 center console wiring harness - a lot less connectors, I assume. Is that what you mean by bench seat? If so, VIN is 3GCUKREC1FG406375. Thanks!
  11. eBay seems to have removed their part diagrams from their website, and I haven't been able to find the part number anywhere else. Anyone know what the # is for the power and USB wire harness for a 40/20/40 center console (jump seat version)? Thanks!
  12. Thank you! Sounds like I might be able to fit a wireless charger in there and still have the 11 fit then.
