So I bought a new mirror off ebay and when I got it to my supprise it is a horizontal 7 pin connector in the rear. It has two map lights, auto dim and I think a light sensor to tell the headlights to come on. I was wondering if there is any way I can make it work with my 3 pin connector or do some wiring and figure it out. The broken mirror just has the auto tint. Both mirrors are donnelly.

Any help is greatly appreciated

Cheers.
