I thought I would pass on some information I learned while replacing my broken non memory mirror with a memory mirror I found at a salvage yard. The harness plugged together fine and everything worked except the up down function. And the left right worked but functioned backwards. After some inspection, I discovered the truck side of my wiring harness was missing one of the wires that controls the up down motor of the mirror with memory.
With a non memory mirror, the up down and right left motors that adjust the mirror share a common wire. The mirror I replaced was on the right side. I had to switch the polarity of both motors due to the fact the mirror controller operated the left right and up down functions backwards. Then I took the white-pink wire coming from the up down motor and soldiered it to the green wire of the left right motor. That enabled both motors on the mirror to share a common wire. I imagine that a mirror with memory functions both motors simultaneously when it automatically adjusts the mirror. That is the reasoning for each motor having its own pair of wires on a memory mirror.
After tearing into one of these mirrors, I would recommend to anyone thinking of adding these power telescoping / power stow mirrors to a truck, go with the manual mirrors. There are so many parts in these power mirrors to go bad, it is frightening. If you manually fold a power folding mirror, you run the risk of breaking something internally. Or you run the possibility of loosening the mirrors arms where the mirror won't hold stable while going down the road. Just my opinion.

 

I added tow mirrors via a local wrecking yard (the local Ford dealer wanted $822.00 EACH!!) and eBay.

The eBay purchase was supposed to be power without fold and memory, but of course, it was memory and power fold. I just "manually" adjusted (hopefully I didn't break it, but I had to see!) the inoperative part. I thought the mirror was broke, and there is no way in this lifetime (or any other) that I'll pay $1,600.00+ for a pair of plastic mirrors (non-power fold/memory).

I'm not sure what genius is running the Ford parts program, but if other parts are similar in cost, this truck will be my last. I don't use one that much, it will be cheaper to rent one when I need it! When a friend with a Porsche laughs at the price of your Ford truck parts - that's a bit too much!!

Sorry to rant, thanks a bunch for the info!!

 

Man, nearly 10 years later and this post helped me out. Forums are awesome. Thank you! Wanted to add some info as I just put a set of 08 memory mirrors on a 12 without memory. Sorry in advance for not taking pictures...

This is on the connector attached to the harness coming out of the mirror itself that connects behind the door panel (same pin numbers for driver/passenger side, the connector has the pin numbers on the back of it):
-Swap pins 10 and 11
-Swap pins 4 and 9
-Cut new pin 4 wire and splice it into new pin 10 wire (I left a little extra wire on pin 4, folded back and taped in case somebody needs to reverse this in the future)

Before cutting and splicing, you can verify which pins are correct by using a paper clip to jumper pin 4 to pin 10 on the backside of the connector, plug it up and test functions.

 

Do you have pictures of the wiring. Doing this on my 2000 excursion the left mirror all wired proper but for some reason the switch on the left function pushing down put my right mirror down lol
