Decommissioned Tahoe PPV: Auxiliary Battery and Its Usage

[nyc7708ems]

Here's a (dumb?) question - and if there's a better place to ask it, please let me know...

I have a 2020 Tahoe LT. I am fiddling around with various projects, most recently beefing up 12V power and access to it. I have a plan going for the aux battery add, and researching for that made me wonder about:

in the left rear, just above the fuse panel, there are two studs/posts. I believe that in the PPV/dual-battery setup, one of these is constant power from the aux battery. My beast, lacking that battery at present, has no power. What I'm wondering is if the wiring from the engine compartment to the rear that WOULD supply power is there, or where to look and see - and, if not, is there an "easy" way to run that? It looks like the "X1A" and "X2A" in the upfitter diagram for X50E (Fuse Block - Battery Auxiliary) would be the front end of those lines (page 3-44 in the 2018 Upfitter guide - 2020 for some reason doesn't have the SUVs in the Upfitter selections) Attaching the pages for quick reference.

You and I have the same question and if possible what size wire would need to be run for it

the 2015-2020 are the same but the separate 2015-2016, 2017-2020 I saw the same thing but doesn't mention the wire size which would be helpful. There is 2 blunt cuts one is a 50amp that goes to the center console, the other is 100 amp connected to 1 of the rear power distribution studs.

Well a couple of weeks ago the auction didn't work out since I was working a Ham Radio Fest in Plant City FL. I lose out. On the other hand my wife did sign off a on nice looking 07 Red suburban LS which I picked up Christmas eve. Good condition but has dry rot tires and crap rims. So I'm ordering PPV steel rims and new tires. Also will need a service. wife put me on a budget so I don't go crazy spending.

Were you able to find a decent deal on PPV wheels? I just bought an SSV and was thinking to just get a second set for it, but the factory 17” PPV wheels I’ve found are nearly as expensive as halfway decent aftermarket aluminum wheels.

Edit: D’oh, just that I was looking at the date of the most recent post, not realizing that the date of the post I was responding to was from ‘22. Still, if anyone has any advice on sources for nice PPV wheels I’d appreciate a link.
