Does what it says

Reviewed By Taylor M (MESA, AZ) Reviewed for a 2014 GMC Sierra —1/26/2015 9:06 PM

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!
