Anyone know if a tow mirror with heat/power/turn signal from a 2011 will retrofit onto my 2012 with the standard mirror with only heat and power? No big deal if the signals don't work but will the wiring harness for power and heat plug into the tow mirror?

 

I can't speak directly to your question, but last spring my mirrors on my 2010 Ram 3500 fried and they were replaced under my extended warranty. (glad I had one). I was talking to the mechanic who replaced them and he told me that the new mirrors were from stock which would fit on a new vehicle, so I presume they are inter-changeable.

I had mine replaced at Eastside Dodge so I presume any dealer in Calgary could give you some free advice. Mine was a Laramie by the way.
