OK. I was forcing that round metal thing that looks like a connector (at the very base of the mirror shell) and I couldn't get it to come off. Looks like I should force it harder :)
Actually, I will wait until I get my replacement mirror so I can see where the existing cable is supposed to...
I'm also trying to replace a mirror. Thanks for the info.
One question - do you have to take the interior door panel off in order to access the power mirror connector?
Thanks!
