2015 directional and tow
 

i want to get tow mirrors for my 2015 sierra and the stock mirrors are power and heated but no directional. i am wondering if anybodys know if i buy tow mirrors with directional will they work? not sure if the wire is there already or not.

If I'm not mistaking, the mirrors plug right into the power window swith - otherwise known as a "driver's door module" to the technically minded :P

Sure, if you buy the dealer mirrors designed to be an accessory add-on, or an "after sale" addition to the truck, they should theoretically work with the provided instructions. To my knowledge though, you cant' get power folding tow mirrors, only power/heated/turnsignal + tow style.

Should theoretically work though. Probably.
