I installed the switch and harness from pgamboa in my 17 1500. At 1st the switch's amber light wouldn't light up and the dash light wouldn't illuminate either. Double checked all my wiring and the grey wire that connects to the white bcm plug wasn't fully seated. Heard the "click" when I reinstalled the wire. Now everything works as it should. Haven't wired up a light bar yet, but the switch and the light on the dash both light up. So guys that are having intermittent issues with your switch double check your wiring. Just a heads up.
