Chevrolet Suburban 3500 Questions

[Geotrash]

Also, I stepped out to the garage this afternoon and unfortunately, I don't have easy access to the area you're trying to sort out:

Hello All, recently purchased 16 Suburban 3500 LS. It was a homeland security vehicle. Wire under radio dash is cut. Everything works as it should except the USBs below radio and in the jump seat.

Does anyone have a photo of what this is to look like or know what this goes to?

I have searched this forum and the web but can not find dash and consul or jump seat wiring diagram.

Please help. Thank you all.

Hello Bigburb3500, appreciate your help with this. Thanks for the welcome.

Its located right under the center left. Under the drivers temp control knob close to floor.
See attached photo with red arrow.

Like Geotrash, I will not be able to access the area today. I will try to as quick as I can but that area will need some disassembly and a bit of time…
Can you follow the other side and see if it goes thru the firewall? I wonder if you have some sort of terminated wire in the engine bay too. It could have been to power govt computers/lights?

Also, note that this looks like a mini usb connector. My guess is it originally went to the USB outlet at the back of the center console.

Great eye! That might just need plugged in or a small extension to make the plug work.

I found the Up-Fitters manuals, too. This will have everything he needs to sort it out.

Yes, this is the jump seat wire harness that needs to go to front under the radio where the cut is to connect and get power to the jump seat USBs.

Thank you for all your help...I will keep searching and trying to figure this out. (love this rig, itll be much nicer once I'm able to charge my phone and get the apple carplay to work)

All I really need to know what the cut wires (attached photo) used to look like before they were cut. What type of plug or plugs did it have.

For example if I can find a photo like this drawing attached (from center consul) where we see where it goes and connects.

As my plan is to remove the jumpseat and replace with center consul but I will need to figure out the cut wires first so I can connect the center consul.

I wish you luck finding one. I just realized one again in this moment how old I am - even when I do have a photo, I find the wiring diagram easier to work with because when I learned to work on cars, photos were hard to find.

That said, Crutchfield usually has some good photos from installers. Here's one for the 2018 Suburban 1500 LT, which I imagine to be similar, even though yours is an LS (they didn't have photos from an LS).

Might be worth a trip to the pick-n-pull to see if you can pick up the harnesses and splice them in. The body on the 1500's is identical to the body on the 3500's.

Thank you...exactly what I need...my cut wire/harness is this exact wiring you provided in photo. I will try and search for more detailed photo. I called my local pick and pulls but nothing newer the 09 tahoe or suburban on the lots.
I wish i could understand the wire diagram.

Maybe this will help a little bit.

Team, appreciate all your help. I have not given up and think Im getting somewhere. Found some photos of what my cut harness is to look like.

Basically what I see is my Harness that was cut has plug or plugs (connectors) that go from Dash to Jump-seat or Console.

Now I just need to find part number of harness that goes / fits my 2016 Suburban 3500 HD LS.

Please see attached photos. Looks like the same cut on mine. They just cut it when removed.

How do we look up part number for this harness and know if it will fit my Suburban.
