    I am interested in adding signal mirrors to my 08 sierra sle. I have been reading the posts here and i have a question.
    Is the wiring harness already there for a plug and play type setup, and if i were to find a set of denali mirrors with power fold, auto dim and puddle lamps how much would be involed in making these features work?
    Thank you in advance for your time.

    I have the Muth Mirrors on my 08 Avalanche and I had them on my 02 Av. I did have to tie into a wire in each door The hardest part was getting a wire through the door harness. But the whole thing took about 45 mins for both sides...

    Wire for what function?

    Op, powerfold will not work without getting the appropriate switch panel and there may be some wiring involved with that...can't be certain. But I know for certain that the power/heat/signal options are plug-n-play.
