I purchased a Invisicord for my 09 GMC Sierra. The instructions from the Invisicord site say to tap the yellow heat shrink to pink wire in the mirror harness and black to ground in the mirror harness. Problem is there is no pink wire! I tried using a voltmeter to find the power wire, but I never used one before and Im not quite sure I know what Im doing lol
Does anybody know what wire is the power?
Is there a wiring diagram on this mirror harness somewhere online. I searched and couldnt find anything.
below is a pic of the harness and wires.
