Tow mirrors

[2015duramaxHD]

I have a 2015 Silverado 2500HD, and it did not come with tow mirrors... I know, ridiculous... Anyhow, I ordered a set of factory tow mirrors. I drilled the 4th hole and installed them, they plugged right in and look great. Now, the dumb thing I did was forget to see if there is a signal wire on the vehicle side of the harness, because the new signals on the mirror don't work. Does anyone know if the trucks come pre-wired for the signals in the mirrors? If it does, do they have to be "turned on" by the dealer? Thanks!

I installed them on mine. The signal does not work. I have read a number of threads about this issue. If your previous mirrors did not have signals, it appears you need to replace the door wiring harness to make the turn signals work. Let me know if you come up with another way.
