Attention: TDR Forum Junkies 
All need some help on my install for the gauge backlighting.
I have the A post mount in with all gauges working except for the backlighting. I used the wiring harness from Isspro so I could dim the gauges to match the other cab lighting.
Tapped a key on hot, a ground by the parking brake, tapped the tan wire behind the headlight switch with the shorter end of the harness. This tan wire also dimmed with the roller switch next to the headlight switch.
Ran the longer end up to the gauges being a black ground wire, red key on power wire, and the dimmer orange wire. Did I use the wrong wire for the dimmer? Thought I followed the directions correctly that Genos sent with the gauges. No backlighting on any of them.
