Installing Tow Mirrors

[samtervo]

I'm installing new tow mirrors on my 2006 Chevrolet Silverado 2500hd WT w/o any power options. The new mirrors have turn signal indicators and reserve lights on them and no other power options. I have seen in multiple places online that I can wire them to the BCM under the dash. But I'm seeing conflicting information about were to tie in at. I've seen that the left mirror turn signal gets wired to a light blue wire and the right mirror turn signal gets wired into a dark blue wire. Then the reserve light wire goes to a green or light green wire. If someone could show a diagram or a picture of where to tie in at that would be great. 

 

Thanks!
