I have a 2007 Tahoe. I do quite a bit of towing with my Tahoe. I would like to install the towing mirrors similar to the ones that come on the late model 2500HD pick up trucks. I was told by the dealer that it's a bolt in item but it will not connect electronically. Has anyone done this conversion? and if so, were you able to connect them electronically as well? Thanks for your responses in advance.
