Works flawlessly

Reviewed By David P (Silver Lake, KS) Reviewed for a 2013 GMC Sierra —11/6/2013 5:21 AM

Plugged in to test port in it arrived and haven't removed it. It works just as its described. Only draw back is there is a blue led light that stays on and lights up the cab. Thinking of putting black fingernail polish over it to block the light. Because of the light issue four stars.
