AUX Upfitter plug no power - 2012 RAM 5500

[TKA99676]

Hello RAM experts!

I got a cab-chassis 2012 RAM 5500 with the standard installed AUX switches in the panel. (4 buttons)
I have done extensive research and measuring with my multimeter, bought the OEM wire kit, found documents explaining it all - still no joy.
I do not have power in the AUX PDX fuse box, or at least I can’t figure out how to get power there.
The buttons are light up when pushed.
ALL fuses are good, main fuse box and AUX fuse box.
I am certain is is something super simple, I just don’t see it.
I wonder whether I would need to install a jumper plug to connect power to the AUX PDX fuse box…
I found a document which spells it all out… for an electric-geek
I have a NON-PTO, diesel, manual transmission truck.
Anyone any experience, suggestions or guesses!?

Did you figure this out? Where did you find the wiring kit?

Hi!
Yes, I ended up figuring it out.
Basically, it was working as advertised.
When I tested it, I must have made an error of some sort.
I ended up going through everything step-by-step and voila!!
All good!
Fuel transfer pump is AUX 1, and that’s all I needed.
All of my research was spot on.
The only thing is, 2009-2012 are apparently a bad year for any electrical upgrades.
But it is what it is and I am happy with it.

I got the wiring kit from the local Dodge dealer, parts department.
Gave them my VIN and $130 one 6” wire
