Can I Upgrade to Power Towing Mirrors if I Have Manual Mirrors

Question:

I have a 2014 Chevy 3500 WT chassis, I want to add the heated mirrors to it, I was going to look and see if the harness is in the door for it, the truck does not have the rear defrost option but I am assuming with a new dash switch and relay if the wiring is there I may be able to add this feature? I am also curious if I can have the turn signal option, the rest of the power functions are not necessary for my truck.

In some cases, vehicle manufactures pre-wire the additional mirror functions to a connector inside the door. If you can locate this connector and test each of the functions to see which are equipped, you can then determine if the K-Source Custom Extendable Towing Mirrors w/ Turn Signals part # KS62093-94G will work for you.

If you do not have the turn signal and heated/power mirror wires ran into the connector on your door, you will need to use the the K-Source Custom Extendable Towing Mirrors part # KS62077-78G. These mirrors have a manual adjustable mirror face in addition to spotting mirrors for reduced blind spots.

I have attached a installation video in addition to a photo of what these mirrors will look like while installed on your vehicle for you.

Got here by Google. Have around the same question. 2014 gsm Sierra, added power tow mriorrs[not power extending]. Replaced door harness, got new switch, and of course mirrors. Installed and they look great. Turn signals work. I have power to the switch however the switch does not light up and the power mirrors do not operate. Any advice would be great

Were the stock mirrors power units? I'm not sure there's a way to activate this circuit correctly on your Sierra if the original mirrors didn't have this function.
