2025 Auxiliary Switches.

[Xflight29]

Does anyone know if the 2025 Rams with auxiliary switches for power distribution, hook-up like the 2020+ do? Where you need to jump one port for another to have a pass-through for interior power

Looks to be the same.

Except the 2025 has only 4-Aux switches (14" screen per Jimmy07). The doc is dated 2025 but only shows the 6-button PTO and non-PTO setups.

The body builder info is incomplete, they haven't even posted the wiring diagrams showing the Aux PDC, frame, and pass through wiring.

Only when equipped with the 14” screen. It’s still 6 switches with the 8.4 and 12” radios.

Correct

Yes, thanks for the clarificaiton.

OP has a Limited, which I believe comes standard with the 14"?

Have you figured out how to add the 4-button AUX panel if the truck has the trailer knob and switch prep wiring? And perhaps why it can't be optioned together?

ETA: Never mind, I just saw your post in the other thread...

Off to find the other thread. I have the "Auxiliary Switch Prep" which was to come with the trailer knob. As far as I can tell there's no passthrough, but there is an aux fuse box with 3 fuses and 3 relays. Hoping there are pigtails somewhere. I wanted the tow camera and liked the idea of the trailer assist, but I figured the aux prep made it a no-brainer. Wondering what "aux switch prep" means at this point.

Every diesel has an AUX PDC with those 3 50A fuses and relays, they're for the auxiliary electric cabin heaters.

Ah - thanks, didnt know that. I'm coming from an 08 so I've got some catching up. So still trying to find out what "Auxiliary-Switches Prep" is supposed to mean then?

BTW - for posterity, the other thread is here: https://hdrams.com/forum/index.php?threads/2025-ram-3500-limited-option-missing.19293/ - same issue I'm having.
