has anyone bought tow mirrors from K Source. i got these mirrors for my birthday and cant find any info on them.my truck is 2014 chev lt with dl8 and ayo for rpo codes. these mirrors are power adjust , heated and power fold. i know i will have to get the ryz harness for the light function and a power fold switch, but could someone tell what door harnesses i would need. i know pgamba is the go to guy but i am up in canada, so if there is a gm harness i could buy in canada could some one give me the part numbers so i dont screw this up. i do have them installed and plugged in and the power mirror functions properly and so does the heated part.
