Where to get power for gauges?

Chipdog · 08-17-2001, 06:47 AM

I hooked up two gauges to a Gauge Cage in the A/C vent. Everything is set up but the power for the gauge lights. Where do I tap into to get them to light up when the lights are on only?

Thanks for the help

Find a dash light wire and splice into it. There should be a light wire for the A/C controls right there, so you won't have to run a long wire.

Use a DMM and find out which whire is controled by the rheostat. Thats what i did, and it works fine(4 years and still going). For ground, splice all the wires together and use an existing mounting screw or a new self tapping screw and secure the ground to the frame(the stereo bracket actually has a stud to use a nut with a star washer) Just remember the ground must be 100% or you will have major problems.

I just did this 2 week ago, i tapped into the wire for the ac controls light, have to take the controls loose to see which wire but then just tapped into it and it works great even dims. i did like prpl said and spliced them together and has worked great.

Chipdog-
The A/C light works well, as does the ashtray light.

Patrick-
Hey fellow Ventura County Person, I always recommend finding a circuit at the fuse box that is switched when the key is "on", but you could use a meter to find a wire outside of the fuse box. Fused would be better, though.

Take care
~Chris
