Auxiliary switch hard wire

[Bjsorrell123]

Ok so please humor me for a second. I know there are hundred threads on this however I’m looking at trying to simplify this. 2020 Ram 3500 bighorn. Comes with aux pdc however it’s not wired with aug plugs and pdc is empty no fuses or relays.

Question : Can a harness of 6 wires be run from the switches inside the truck to the outside and be wired into an aftermarket fuse and relay panel?

Can? Yes but its not that straightforward.
Do you have the factory instrument panel aux switches?

Yes I have the switches and yes alpha setting have been changed and the switches light up
