Hi all,
I have a new to me 2008 F-250 Lariat Crew 4x4. The power mirrors were not working, and what I've found is that someone has replaced the mirrors with what appears to be 03-07 model mirrors. They did not have it connected, since the truck has the male 22 pin connector, and the mirrors have the female 10 pin connector. I have seen various wiring diagrams and pin outs on many posts for those upgrading to newer style mirrors. None of them seem to match the colors of my wires. I have narrowed down the turn signal, marker lamp, and ground. I believe I have 4 connections on the truck for the power mirror motors, and only 3 on the mirror connector. Can someone help me out with the mirror motor and heater connections? I'm thinking the motor on the mirror may not work since none of the other wires respond when I apply 12V to them. Also, i would love to keep the connectors, so does anyone know where I can get a female 22 pin pigtail and a male 10 pin pigtail?

Mirror connector:
Black = Ground
White = Marker Lamp
Brown = Turn Signal
Black/White = heater (I think ??)
Violet = ?
Yellow = ?
Green = ?

Truck Connector:
Yellow/Orange = Telescope out
Gray/Blue = Mirror right
Gray = Mirror Left
Blue/Green = Mirror Up
Brown/Green = Left Turn Signal
Black = Ground
Violet/Green = Marker Lamp
Violet = Telescope in
Green/Brown = ?
Violet/Brown = ?
Brown = ?

 

Do the 2008 mirror's have the proper connections?

If not you might need to find copies of the two different year mirror schematics in order to wire the truck or the mirrors to work together.

Finding an EVTM for each year would be my recommendation to see how they were wired from the factory.

It might also be possible to re-pin the connectors, you'd need to scour scrap yards for trucks with the same power mirror options. You'd need to cut the individual wiring harnesses. Unless you find one of those years nicer F-Series in a DIY scrap yard cutting a working wiring harness wouldn't be possible otherwise.
