I installed my new A-pillar gauge holder and all of my gauges. All of the sensors for everything is hooked up and working, but I need to find a 12v ignition on, and a 12v parking light on source under the dash to light up the gauges and power the tranny temp unit. Any pointers or tricks to make this easy? TIA :-)

 

For the 12v switch on, use the cigar lighter wires. For the dimmer, use the brown w/ orange tracer wire on the headlight switch.

 

Thanks for the heads up! Everything worked 'cept for the brown wire with the orange tracer. I wired it up and had no lights. Using a multimeter I found that the bottom orange wire with brown tracer had what I needed to light em' up. Thanks again.

 

You found the right one.
