I'm looking to ad some HD mirrors on my 2000, I want to add the ones with the turn signal in them, my truck didn't come with that of course. Dealer says can't be done, have to have a module in the door that ties in to the bcm, I looked at an 04 that has them and it seems that I can wire then in to the turn signal relays under the hood. Has any one done this? I searched maybe I used the wrong keyword.
