If you buy the first part what does the second part do? The first isn’t the same options as mine, but I did find what I believe to be the correct part.

The second part is what you use to connect 3rd party accessories to the (new) PDC to be controlled by the aux switches.
I don't of anyone that's been able to buy the vaporware Aux PDC kit 82216450AB from Mopar.
I was able to get one from BAM, back in March of 2023, but what they sent me was a unit that someone else had returned because it had the wrong buttons for his truck. I know because they didn't even open the box when he mailed it back, and it still had his order forms, phone/email and credit card info in the box, ready for me to steal his Identity. I won't buy from them again, but I can confirm for at least a small period of time that part did exist.
I just ordered the pins for this and the mopar aux switch kit, dealer is going to flash the computer on the truck. They added the sales code a couple days ago just need to actually have it flashed. I’m hoping I can find the right tool to crimp the pins and do it without messing up the xy125

Honestly it’s luck of the draw at dealers or online sellers. Best place would be posting in FS section or eBay. I had to get mine from someone on here cause like the issue your having they are all out of stock even when they say instock

Try changing the last letter to B or C or so on. If there is a change in manufacturing they change the part number letter sequence.

Hi all,
Just adding my installation for my 2020 Power Wagon. This thread has been very helpful! I had to design a custom Aux PDC since PWs don't have the Aux PDC. Please forgive me, this post was originally written to a Facebook group so a lot of the info is redundant for this thread. I was elaborating there for people that may not be as familiar with what's involved. This thread is fairly long, so it might serve as a type of summary for new readers I guess.
I have another 10 pics or so related to the installed PDC but didn't add them since I am limited to 10 pics on one post. If anyone wants those as well, I'd be happy to post them.

I was elaborating there for people that may not be as familiar with what's involved. This thread is fairly long, so it might serve as a type of summary for new readers I guess.
- Starting with the switch panel itself (pics 1-3), the install is pretty easy. The exact part number for any given truck can vary, depending on which switches you need in the panel you are replacing, and some cosmetic differences (glossy vs matte). You need to locate the correct part number and I've lost the reference I had somewhere from another thread were someone detailed it. There is a "decoder" for the part number in the thread above I think but many report that it didn't work for them. I did not use the decoder.
- (Of note, both my screen and my trailer tow switch stopped working after being disconnected. I have no explanation for that and do not attribute it to anything with installing the switches itself, maybe they were going bad (the screen had gone blank before at times).
- With the new switch installed you need to add the wiring for them. There is existing wiring in the harness that wires all six switches to the body xy125 connector in the footwell area on the driver's side. These dead end there with no wires going out of the mating connector into the engine bay (for trucks without the auxiliary PDC which I believe is not an option on Power Wagons). The first option is to pick up the wiring on the mating xy125 connector by obtaining the correct terminals crimping them onto your wires and inserting them into the appropriate unpopulated mating connector. I was originally going to do this as it's perhaps the "cleanest" approach. The problem is that connector already has a lot going through it and I didn't want to mess with it and break something. It's also hard to get to and requires 2 different terminals for using all 6 switches. (I purchased both needed and have them unused).
- The option I went with is wiring directly into the connector at the back of the switches. (See pics 4-6). This means unpinning the dead ended wires there and putting in your own. For the switches I used a 6 conductor wire with 6, 20 gauge circuits which worked well. I originally tried 18 gauge but found the wires troublesome to seat into the factory connector. I drilled a hole in the unused plastic blanking plate for the clutch pedal, installed a strain relief fitting, and ran the wires into the engine bay.
- With the switches installed, you will need to use AlfaOBD or something that lets you change the configuration for the truck. There are 3 options I think I enabled, these are covered in the thread above. Done correctly, you will have the commercial settings option in your EVIC. This lets you change the configuration of each switch on how it's powered, latching vs momentary, and retain last setting. This really cool feature is what really makes using the factory switches better than any aftermarket options, aside from everything looking oem.
- Now the Auxiliary PDC itself. My truck did not have a factory aux PDC like the diesels have, and not sure if PWs can even be ordered with them (at least in 2020). So I set out to design my own. I ordered the parts I thought would work best, basically a 6 relay / fuse box, a power distribution block, and a ground distribution block. I designed the bracket to hold everything from 3/16" aluminum plate using Fusion360 sheet metal design and sent it off to OsH Cut laser cutting and bending service. Great service, and for $100 delivered, I had a very strong bracket. (See pics 7 - 10). In the end I had a fairly compact, very strong bracket that had 2, 4 gauge wires for the power and ground, 6 pig tails capable of 30 amps for each output, and a 6 pin connector for the switch bank grounding inputs.
- For the 6 pin multi connector switch inputs, I used Deutsch connectors which I found really great and easy to assemble. I would use them again for all low voltage / low amp connections in vehicles.
- I made sure to ground the bracket itself since it's conductive, and the main ground runs directly to the battery negative. The power feed goes directly to one of the unused power posts in the battery connector through a 200 amp fuse connector. You generally want the fuse as close to the battery as possible. I had to cut the plastic shield a little to use the fuse and the connector sticks out a little, but has it's own protective cap.
- I'm pretty happy with how it turned out. There are some things I would change if I had it do over. Accessing the pig tails will be a bit of a pain as they are short and tucked under the cowl. I would have made them a bit longer Clearance for the relay box cover and cowl is tight, and accessing the clips to remove it is a pain but doable. I would redesign it to move it closer to the battery and/or angle it forward for easier access. It's all tucked in pretty nicely though in the factory location, and testing shows it all works as intended.
I have another 10 pics or so related to the installed PDC but didn't add them since I am limited to 10 pics on one post. If anyone wants those as well, I'd be happy to post them.

Looks great
Man, I’ve got my aux switch panel already and have been planning to order the PDC kit, but just haven’t gotten around to it. This looks like it may be a better way to go though.
Do you have a parts list you’d be willing to share? And maybe the details to order one of those stainless brackets?

You have the Power wagon or 6.7L?

I have read all 30 pages of this thread and a lot of great information. It looks as most have done a DIY fuse box when adding the switches. A saw a few recent post about the aux switch kit that is available - is that something that just recently became available?
I have a ‘24 Power Wagon and would like to add these for a factory look. Will the kit work?

I have been trying to find out if the kit that says up to 2023 will work in a '24 model.........I have posted and asked in several different places--with no answers. I also want to add this to my '24 Laramie......

From all the wiring diagrams I’ve seen it’s all the same from MY19-24. The switchbank itself has a different finish from MY20+ (I could be wrong in the year) but that’s it.
