Always on USB Power?

redwngr · May 28

Interesting.

My 21 has 12 v power ports. (and the 120V shared 400W outlets)

2023 owners manual shows 12v power ports.

I have a '23 being shipped. I'm curious to see if it has 12v port(s).

No standard round 12v ports in my '23 LTZ Z71 crew. Just USB in dash and console. 120v in console and bed. Has technology package. Running my V1 off the Savvy adapter in the OBD port.

Decided to see if there was any info about this in the fleet order guide.

It shows the 12V outlet is only installed/available on low trims.

On sierra

First column is the 'pro' trim.

On Silverado it comes on the WT, Custom and Custom Trailboss

So it would be in the Owners Manuals -- and not be on the high trim trucks mentioned in other posts.

Perhaps also explains the OM section discussing fuse location changes -- and the lack of available connection on higher trims that will not have the 12v pot.

Guess I'm won't be running the 12v cooler with the new truck when it arrives

Yes, I was pretty shocked on my ride home and realized I had no 12v port. Bizarre. At least there is a 120v outlet that perhaps can be used for the cooler?

He could, if'n his cooler only pulls a tad over 3 amps. That 120v receptacle is about as worthless as t!ts on a boar.

I assume nobody has found a constant power source on from the passenger side box?

I would like to install some extra footwear lighting on my dad's 2023 LT silverado. Using the X1 BCM connector's pin #1 12v as a trigger for the relay, and power the lights via the F28. Avoiding running a wire from the battery.

I put my meter lead down the empty fuse hole to the circuit board, while the truck was off, and was able to see 18v on the meter.

The F28 socket on the circuit board DOES get power constantly.... but the prong to plug something in to it is not present.

Trim down a 1/4'' male spade terminal to fit the hot side in the box and an inline fuse to protect the circuit at the box.

It would need to be soldered to the board. Not feeling that too much. I might have tried it if it were my truck.

I ended up mounting an auxiliary 5v port with full time power. Works great. But yes, it's extremely frustrating they took away the 12v outlet, and the ability to select full time power with the F27/28 fuse. Dumb move.
