Another towing mirror question!! sorry

[hegsz71]

I've read more on these damn things then my boss would ever want to know, but I have a buddy who is wondering a few things:

His truck 2015 Gmc Seirra 2500 all terrain with the small power folding mirrors

 

If he orders a set of tow mirrors does he just need the harness and not the control switch or does he need both?

I'd recommend a bit of wait time. GM is releasing those mirrors as an accessory in chrome (for power fold) and black (non power fold). I am not sure what else is involved in their kits coming though. Being an All Terrain I'm doubting on door harnesses.

Got the kit install the black mirrors vack up light doesn't work and no amber running lights they do flash when you unlock the doors
