I found a newer GMC truck in the junkyard I forget what it was, definitely a loaded luxury model. It had a slightly larger mirror than mine with two reading lights on the bottom, along with a better tilting system/lock. It had already fallen off the windshield and was hanging by the wire, I'm wondering what I will need to do to fasten it to my Dakota windshield properly. Also the wiring... there are two large orange and white wires, then a smaller black one. I would guess positive and negative, then the 3rd must be for dim? There is no security system light on it or temp stuff, all I can think of is a dimmer wire.
