brown is the hot wire on the mirror

 

Got it to work. Thanks for all the help. I used the mini screwdriver for glasses and was able to open the hole enough. Hopefully it didn't damage the plug to much. It does look mangled but works nonetheless! Thanks again.

 

Congratulations Diver.

 

Congrats! Glad to be of some assistance.
