Well I got the mirrors and I got the passenger side installed last night. Didn't get any pics because it was dark but I'm going to take some when I do the drivers side. My setup differs from mjonesjr's a bit. The wires coming out of my '04 mirror are very long, with the harness end of it mounted behind the speaker. The wires on the '06+ mirror are short - they only stick out of the mirror a few inches, and it has a different harness. So I used the long three wires and harness from the stock mirrors and cut the harness off the new mirror. For good measure, I soldered and shrink tubed the wires and wrapped them up with electrical tape. The only tricky part was finding crap around the garage to use for washers.
The only issue is that for whatever reason, when adjusting the mirror, the left/right mirror controls are reversed. When I move the adjustment switch left, the mirror moves right, and vice versa. Up/down is fine. No biggie, especially since I was willing to just bolt the mirrors up without power, so I'm not complaining. It's just strange since my wiring job is good and I didn't cross any of the three wires....
