I pulled off a cracked autodim mirror off my 97 XK8. I found this may not have been the orig mirror. It was not connected. It had no connector on the mirror side and only 3 wires comming out of the mirror. Wt, bk, grey. The yellow female connector in the car has 4 wires. Pink/bk, br/bk, y/wt, r/wt. This is a donnelly I (E8)011530. I have a mirror that my brother gave me that is like new. Looks almost identical, same numbers but it has a knob on the back and 8 wires. Has anybody spliced an 8wire into a 4 wire that you can tell me how and what wires into what. Thanks, Steve
