Bought a 2015 RAM 1500 Express (love the painted bumpers) in February with the towing package (integrated brake control, 7 pin connector, 3.92 gear ratio), but only had the basic heated mirrors. Needless to say I couldn't see around the sides of our 30' TT while towing.
I found this thread and ordered the mirrors
here last Friday with the free shipping option. To my surprise they arrived the following Monday afternoon.
The first side took me about 40 minutes from start to finish. I took my time removing the door panel as I didn't want to snap any of the plastic clips. I was not expecting to be able to use the blinker or puddle lights, but the door module inside did have the pins for the white connector so I connected both wiring harnesses from the mirrors. After assembling they did not work however. The second side installation took only 20 minutes as I knew now how everything came apart.
I saw the following post on a previous page so I gave the dealership a call.
Sales code needs flashed into the truck at a dealership. LEB and LEC will get the turn signal and the puddle lights working.
They had no idea what I was talking about and said it's something they couldn't do, but I was passed on to someone else anyway. This new guy said it was probably possible and to bring the info in the quote above and it would be $25 to flash the codes, but he couldn't guarantee it would work. I had him check my VIN and told him the pins were in the door module so was optimistic it could work.
Anyway, after 20 mins at the dealership and $25 later I had working blinkers and puddle lights. Very pleased.
The mirrors look great and do not look like a cheap aftermarket item. They fit well, were easy to install, and best of all I can actually see when towing. For anyone that doesn't want to use clip-on towing mirrors and prefers a factory look, this is the way to go.
