2014 DC TRD OR

A quick second question, been looking at a travel travel trailer and was wondering if the taco had the wiring run but not used for heated mirrors and turn signals on the mirrors. I was looking at some replacement extending mirrors that had these options but didn't know if the wiring existed from the factory to tie into.

I did notice that some option packages on 2014's had heated mirrors but was wondering if at the factory they still included the wiring in the harness.

Thanks again.
