@@jmcknight63ify For the 2019 Ram 3509, the part number for the kit is 68398184AB. The description is "Kit, Auxillary Power Distribution Center." I believe Ram changed the kit around 2022, but I don't know the new part number.

@@Phil-km4up That video was filmed shortly after I bought the truck. I have reconfigured everything. The Banks iDash is installed in a custom mount in the a-pillar. The aftermarket TPMS system is gone because I am using the truck's trailer TPMS system. I got a different mount for the trailer backup camera so it is more on the passenger's side.

@@threeriversdent I did not make a video on the other wires. I believe they are related to the transmission PTO feature which my truck doesn't have.

@@KRAWLSTARS I believe Ram issued TSB 23-029-18

@@alstuart That TSB has been around for a while and is for the 1500 Ram. Are you saying that you used that TSB for your 2500/3500?

@@markruddle4252 It's one of the pigtail wires that came in the AUX wiring kit which is part number 68398184ab

@@alstuartgotcha thank ya. I need those spade connectors. The aux buttons were already installed.

Yes, it's documented in TSB 08-031-20 which states, "The upfitter auxiliary fused wires are not populated on the rear of the chassis wiring harness equipped with Instrument Panel (IP) auxiliary switches. The wires are located on the right side of the rear chassis cross beam, above the fifth wheel."

I believe it has something to do with the PTO option on the transmission, but I never did make that video. Sorry.

The site i think he's talking about is the upfitter site, which I can't get into either. They want me to create an account and they keep refusing me asking what my business name is...

The beer is at my house, and you're welcome to come partake!

The part number for the wiring kit is 68398184AB. I do not know the part numbers required to install the power distribution box under the hood. I did see some discussions about retrofitting the power distribution box on HDrams.com/forum.

For my 2019, the part number for the wiring kit is 68398184AB. I believe in 2021 the part number changed because the pinouts changed a little bit.

That's great! We are currently traveling all over the United States with our fifth wheel.

@@alstuart currently near Wickenberg AZ waiting for our Camp host spot to open in Oregon. Is that a 27-5L?

@@TheBuddy1939 Yes, 27-5L. We really like it.

Glad it helped!

I ordered my truck with the AUX switches installed at the factory. I don't know the part number, sorry. I believe I saw some posts on hdrams.com about adding the switches. Try this post. hdrams.com/forum/index.php?threads/diy-add-aux-switches-to-19-ram-2500-laramie-6-7l.13229/page-4#post-294649

I do not know how the 2018 AUX system is wired, sorry.

I will give you a detailed answer, but first I need to know the following: 1) What is the model year of your truck? 2) Do you want to be able to turn on the plow light when the truck ignition is off? 3) What size fuse is required for the plow light?

​@@alstuartit's a 2020 Ram 2500 with the aux switches installed from the factory. Id like the light to shut on and off with the ignition. It's a Buyers Products LED warning light and only draws 2 amps @12v, 24watts.

@@billgammon8734 I wouldn't install a relay because Ram has already installed relays for each of the AUX buttons. Each AUX button supports up to 40A, depending on the fuse. I recommend the following: 1) Install the pink/brown pigtail in the upper left port #1 of the dark-gray connector under the hood. 2) Install the violet/yellow pigtail in the lower-right port #4 on the light-gray connector under the hood. 3) Splice the two pigtails together. 4) Install the gray Jumper into the port under the dashboard near the parking brake (see @10:29 in the video). 5) Splice a 12 gauge red-colored wire onto the end of the violet/yellow wire that comes out of the gray connector under the dashboard. Run the red wire to the location of the 12v lighter receptacle under the rear seat. 6) Connect an inline mini-blade fuse to the red wire BEFORE the 12v lighter receptacle. Most 12v lighter receptacles are rated for 10A, but check your 12v lighter receptacle requirements. 7) Connect the inline fuse to the positive terminal on the 12v lighter receptacle, and find a suitable ground location for the negative terminal on the 12v lighter receptacle. 8) If your plow light doesn't have its own fuse, I recommend installing a 3A inline mini-blade fuse between the 12v lighter receptacle and the light. This way, the lighter receptacle has its own 10A fuse, and the light has its own 3A fuse. This enables you to plug other devices into the 12v lighter. 9) Under the hood, there is the AUX fusebox as shown @5:01 in the video. From the factory, a 40A fuse is installed for AUX1. I recommend switching to a 20A fuse. You need a LP JCASE (low profile) fuse that is 10mm x 12mm x 16mm. In the video, I incorrectly say you need a low-profile MCASE fuse, but it is actually a low-profile JCASE fuse. On Amazon, you can get an assortment of 40 normal and low-profile JCASE fuses from the vendor named BIOFUSE for about $30. 10) Lastly, you will need to configure AUX1 button behavior in the commercial settings. The type needs to be "latching." The power source should be "ignition." The last state option should probably be "on" so you don't have to press the AUX1 button every time you start the truck. Please let me know if this needs clarification. Thanks, Alan

You're absolutely awesome, man! Thank you!

Everything worked perfectly! Like in your video, my dark grey connector also was missing the little clip.

For my 2019 3500, the wiring kit part number is 68398184AB. The description is, "KIT, Auxiliary Power Distribution Center" so you can look it up for your truck year/model.

Yes, you can configure it so one AUX button controls one set of rock lights and another button controls a different set of rock lights.

I have a Banks iDash to monitor exhaust gas temperature and other stats. I have a trailer tire temperature and pressure monitor. I have a backup camera for my 5th wheel. I have a magnetic phone mount. It's seems lik too much stuff, but I use all of it almost daily.

I bought the aux switch bank with the truck as a factory option.

You're welcome!

Starting in 2021, Ram improved the AUX switch design. They added a ground wire inside the cab, and they added more passthrough wires into the cab. I don't know which battery the aux switch power comes from, but I can try to research during the next week. Here is a great video on the 2021+ AUX system. th-cam.com/video/6seCDodwohg/w-d-xo.html&feature=share8
