Help: DB Gauge Install Won't Light Up
 

Help, I just finished installing my LC-1 wideband and DB gauge kit. For the LC-1 I tapped the turbo timer 12v switched power source. For the gauge I tapped where my OEM MR Gauges are tapped for power (radio harness). I ended up just tapping the actual gauge lines (red and yellow). I am pretty sure red is switched and yellow is lights because the MR boost gauge only has the yellow while the oil temp and voltmeter get red and yellow. Any rate, my LC-1 is getting power and I was able to calibrate but my DB gauge stay blank, no power. One other thing I did was I ground all my wires to the same spot using some crimps. Could the grounding source be causing the gauge not to power or is it because too many gauges are powering off the radio harness?
Thanks

It could be a combination of both. My advice is to double check your ground and test your power source with a multimeter to ensure you are getting enough voltage. Your power connection could also be loose so check that as well.

How do I double check the ground.

just check make sure everything is connected and tight. other than that, i dont see why it doesnt light up. check the wires
