I just don't have the time to explain this the right way, so I will give you all the info I have and hopefully that will help others to do this mod.
Power fold mirror install with the factory power mirror switch.
These instructions assume that you have a very good knowledge base of how to take your truck apart.
This is how I did the install, I will try to make it as easy to understand as I can.
First you need to have all of the parts and misc. installation items in hand.
Remove both front door panels then remove the center console trim and radio.
Remove the right side fuse panel door, cover and bolt that holds it to the truck.
For 2004 owner’s this will be real easy. Why? You do not have the plug in type of harness from the door to the door frame, you have a rubber boot. 2005 and 2006 owner’s this will be the big pain.
Once you have everything open and exposed you will need to de-pin your pig tail you got from Ford (see part number below) You will then take the wires and place them into your factory power mirror harness
and one from the switch harness (make sure you insert them in the correct way) and in the correct locations
(see the wiring diagram) at this point solder 7 feet of wire from each mirror
and one from the switch harness.
Run the wires inside of the door tape them to the factory harness for those that do not have the plug at the door fish the wires to the inside of the cab.
Those with the pug (this will be a BIG pain in the ars) look at the photo of how I did it I drilled one 3/8 hole in each part of the plug (lots of room and slots not being used)
make sure you line them up, pull the wires very slowly
as you do that connect your plug back in and CLIP IN DOWN
I placed my PFM relay behind the in the center of the dash.
Hook it up as the wire diagrams show. Bolt on your PFM test and you should be ready to close it up.
Wire diagrams can be foung here
from another member that did it without the factory switch.
I know this not as good a write up as some others have done but with all of the emails inregaurds to this mod I wanted to get it out ASAP.
