So I have installed and they look great! I would post pics but as I am at work I cannot. however even though the puddle and power adjust functions work, the turn signal and probably heat doesn't seem to function... I was looking on the f150 forums and reading about their pin relocation but I cannot seem to find them on the Expy. I have heard that in the F150s from 04-06 each option (power, puddle, heat, signal) each have a separate ground and since I found two grounds I'm presuming that is for my puddle and power if the expedition is wired similarly to the F150 in that respect.
I know i could just wire the turn signal and heat separately into the defrost and turn signal wires inside the truck but if I could avoid the extra wiring I'm all for it. If anyone here has installed the high trim tow mirrors with the turn signal and heat options some guidance would be much appreciated!
