I am trying to find the wire termination from fuse 100 to the Aux PDC. Did they hide it somewhere in the harness near where the Aux PDC would be installed if it had come from factory? Did they just not pin it on the connector under the main PDC but left the fuse terminals in? I have 2022 Ram 2500 6.4 hemi Tradesman so the aux PDC was not factory installed. It looks like it was used as a run relay for something related to the upfitter controls. I know there is power because it has a fuse and my lazy plow installer used a fuse leg tap as the trigger for western hand held control. See highlighted wiring diagram. It is supposed to be Pink/yellow wire.

Fuse 100 Wire Location When Aux PDC is not Factory Installed

You're doing it wrong
Your plow installer was not lazy they simply used the instructions from western instead of tearing in to your trucks wiring…. Lift the PDC and check the pin out for the wire, i would doubt its there.
@Jimmy07 could likely help.
I appreciate your very quick response. I did not realize that is what western suggests. It is bothersome that an aftermarket company that big would suggest something like that on a brand new $60-80K truck. Serves me right for being lazy and not doing it myself. Just seems like creating more problems with all the salt spray. I bought a new PDC cover and was going to put a connector on the wire and push the wire through a grommet on the new box to help seal better. When they installed they cut a notch in the bottom of the cover that opens the fuse box to more contaminants.
I started researching adding the aux switches and that led me down the rabbit hole of "there has to be a better way to install this control wire" . Since I don't think I will need this to add the switches is it possible to pin out a wire from the connector to make me feel better. Is the pin available on the open market.

The reasoning Donaldson dynamics (Fisher, western and snow ex) and any other plow company do stuff like that is they can tell who is doing the install and having people who may not have the skill splicing in to factory wiring is not always the best goal… you should see BOSS setup they have you run a switch into the cab that sticks to the cluster base…… my plow i actually use # 6 aux switch to trigger the plow lights and as a bonus i can use it to kill my headlights at night and still keep my running lights on.
