I got them on in a matter of a few smoke breaks while making chili and nachos for tonight. It took me half a smoke to pull off each stock and a full smoke each to put the new ones on. I have stock power mirrors. I simply cut the 4 pin connector off the stocks, and wired them to the new mirrors in place of the 6 pin that came with the new mirrors. I still have to run the power for my defrosters, but I dont know where I want my switches yet. The passenger side red wire is the white wire on the new mirror, and purple and green go together too. That way you can unplug them if need be. The drivers side wiring is just matching colors to colored stripes. Blue goes with blue stripe for example.
