Aftermarket tow mirrors

[Shawn226]

So I bought the aftermarket tow mirrors from 1a auto and installed them on my truck. (Express with heated auto mirrors) but I didn't have puddle light or turn signal. When installing them, I saw two other plugs I plugged the second connection into, but no function. Anyone install these on their express and make it work? Or is it just going to be nonfunctional

I want to do the same thing to mine but didn't know if it was possible if the truck didn't come w them. I hope someone can answer this

Do it regardless, because I still have to heated and power adjust functions

Read somewhere that the dealership could flash it to get the lighting functions to work, anyone have any experience with this?
