My truck is a half ton 2005 with power mirrors, I was wondering if it was possible to add the OEM power extending mirrors off like a 3/4 ton truck? Where is the button that extends them? I guess it's a different button setup on the power window switch on the door panel? Does anyone have any pics? I'm wanting them for my 1/2 ton. Any pics would help, I'd really like to see what they look like all the way in. I guess they have turn signals built in also?
