Hey everyone, first post here and reading up on this thread. Sorry for the noob but maybe complicated question im about to ask.
I have a 2014 Ram 1500 SSV (special service vehicle), and it came with the upfitter package and the VISM under the dash. I have just the one upfitter plug in the engine bay, jthe dark gray one so I can run the aux panel for sure, just aux 5 will be useless since i dont have the PTO option. I understand I need the aux panel from a 2500+, but do I need the upfitter wiring package, or will this all be plug and play once i swap aux panels, and run 4 new wires from the gray plug in the engine bay? currently its the blank bottom row.
