Aftermarket towing mirrors

I just put these mirrors on for towing my camper. I definitely like the fact that they flip out for towing then tuck back in when not needed. The original mirrors were only power adjustable, the new ones are heated and they have integrated turn signal. It was plug and play for the power mirror. I'm assuming the two seperate wires are for the heated part of the mirror and for the turn signals. I believe it pulls the common from the main plug harness. My question is has anyone else installed something similar and if so where did they tap their power from?

 

There isn't any wiring in the doors for the turn signals on 07, the side mirror turn signal option wasn't available until 2012.

Connector 1D Pin 4 (Blue/Yellow) (Right) and Pin 11 (Blue/Black) (Left) on the Drivers Side Junction Box probably the best spot to grab the turn signals.
You would need to run your own switch and power for the heaters as that was never an option on 2nd gens.

 

Thanks for the information!
Looks like tapping into the turn signal circuit should be pretty simple. I'll have to try and think of where I would want a switch on the dash for the heated mirrors. Unfortunately no information came with the mirror so I don't know how much current the heated mirrors.
Do you have a suggestion where I should tap in for that?

I generally don't recommend adding anything to any factory circuits that would pull more than 3 amps, I would run a dedicated fused power wire from the battery or stud in the underhood fuse box to a relay and then use a switched ignition source through a switch to turn the relay on.

 

thank you!
