If you leave a device charging or powered overnight does this risk bricking the vehicle?

This post is a direct cable to the 12 volt battery for charging. The terminal base is for a 12 volt clamp.

I'm surprised it is not in the new manual loop as of yet.

Some things are not in the manual. Under the front cover for the windshield wipers is a 12 volt connector suitable for jump start cables or trickle charger. With close access to the firewall you don’t have to unbolt the passenger seat for 12 volt connections.

Phone, GPS, Thinkware camera, CarPlay stuff, communications for HAM, CB, GSMR, whatever - source is yours.

This mounting point has some hefty cables with a 10mm nut, maybe 6 AWG, to this connection point with a “port” that is subtle for a jumpstart or charger clamp.

(Factory convenient? Not for the masses? I checked 2026 manual. I could not find it in my version.)

I routed some 12 AWG fused pairs for two ports, 12 volt cig/USB and low amp hardwire - and one designated for communications radio.

There are two rubber nipples that are located by the passenger firewall. REALLY good rubber that will require a sharp knife for access - something in the consistency of a MOHS equivalent of overcooked calamari.

Two 25 torx screws to remove the panel where the fuse box used to be in the old days.

(The concept of “virtual fuses” is in another information orbit. Analog to Digital to Virtual to Conceptual = Ohms law on drugs.)

The output is easy to the central counsel. Remove the bottom pad and use a plastic panel lifter to remove the Rivian plastic plate.

Thank you, Just finnished installing my Extreme LED light bar. I ran the wire down the driver side of the window and routed it around the air cabin filter to get to the point that you highlighted. It's super simple, just connected the ground at the base of the 12 V power and then just added an additional M6 nut on top of the existing nut to get 12V power. The whole thing took 20 minutes to do! This Light bar has a Bluetooth remote, so need to run wire for a switch through the firewall.

This is not a great picture. It's raining outside, but you can see the light bar freshly installed on top of my rack.. No need to see more wire runs as I did as you suggested.

Can you be more specific about this? “Two 25 torx screws to remove the panel where the fuse box used to be in the old days. “. Since I do t know where that was I don’t have a reference. Also do you mean the nipples I have highlighted here? Thanks

Yes. Those are the ones. The other side is the panel below where the glove compartment would in 95% of the vehicles on the planet.
