Mirrors

[cub 982]

Just installed aftermarket towing mirrors with power,heated& lights on a 2017 GMC Sierra my stock were just regular mirrors with power & heat, get everything hooked up put back together and the lights on them don't work do they have to be programmed or a fuse put into a blank spot any information would be great. Thanks

Did you do any wiring harness customization? What brand mirrors?

[cub 982]

No customization and just aftermarket from AutoShack

You usually need to add wiring to bring new features to the mirror, that were not present on your truck from the factory, like turn signals or spot lights. Not sure how you go about it with your brand of mirror though. Boost Auto sends full kits with wiring harness' and instructions.

Yes, you will need a new door harness.
Here is a great one From HarnessDr

 

When I had my tow mirrors installed, the dealer swapped the door harness with the stock GM tow mirror harness.

HarnessDr also has some DIY options for a lesser price.
