ok, so I am new to this forum. Purchased a 2008 Lariat Limited, sweet truck! My first pick-up. Anyway it has everything and anything offered except Power Fold mirrors. I was told the upgrade is NOT a plug n play, that I must wire the mirrors (which I am not afraid to do). I just need a specific wiring diagram or step by step instructions.

I know the following:
1. Need a relay (not sure where it goes)
2. Need a new control switch (replaces the existing)
3. Need a fuse in the fuse box location for power fold function
4. Need two new mirrors.

anything else?
thanks for help in advance
