I did not look into it. I think from some reading it is possible......
I had a p2 installed in 30 min. biggest issue was getting the cover off the fuse block panel for lack of better term behind the brake pedal. Once that was off, putting the wire harness, then two self tapping screws for holder in. Everything was in. Real easy!
I hooked up my equipment trailer, truck sunk more than I'm used to with 350 lbs of hitchwt. Thats probably the 4000 lb suspension vs the 6000+ ones I'm used too.
Lights etc work on trailer. SO tomorrow we'll see how it tows a 3500-4000 lbs total trailer.
