How to Replace Taillight Wiring Harness 2007-2013 Chevrolet Silverado 

do i need to disconnect the battery when doing this? ...

Thanks for the video. I have a 07 classic body style and was looking how to unplug the harness from the junction box and it looks like the newer version has a better clip than on mine.

Replaced this harness and now my entire driver side turn signals stopped working. Any ideas as to what would cause this?

Great video thanks

I installed one of these, and now my tail light and reverse light come on with my headlights. Any suggestions?
