Lighting is important also heat helps in winter.


The top banks that are empty on my harness are where factory turns are wired in. Be smart and careful when doing the heater both wires are the same colors on both connectors, mine are both grey on tow mirror and both black on factory once i matched the pins i pulled on the black wire from the factory harness to make sure i had the right black wire at the end of the loom to crimp to the correct grey wire

passenger tow

without oem turn signals

drivers side tow

hope this helps you guys
