Assuming you got it out of an Explorer....
Pin 6 RD/YE 12v in Run 7.5A fuse
Pin 5 LG/YE 12v Hot at all times 7.5A fuse
Pin 4 BK Ground
Pin 3 BK/PK 12v routed through the DTR reverse contacts or backup lights switch (manual trans) 15A fuse
Pin 2 WH/VT to Autolamps Sensor output 2, which is a switched ground shared with the Parking and Head Lamp relay coils.
I don't know a thing about that mirror, but it appears it needs to know the lights are on by giving it a ground on WH/VT.
PM me an e-mail address and I will send you the diagrams.
