lol hey,
k so i got somesubs and stuff and there pretty crazy,
and just for the fun of it i thought ide buy a volt gauge

so i got the volt gauge and all that working. but now i figured out, i can light up the gauge to so i bought a little light thing that goes inside the gauge, and i need to find a light source wire to hook it up to! and have no idea where it is

so can anybody help?
hahaha sorry i know this is pretty useless just i have waaaay to much time on my hands and i need something to do

Look in here: http://www.355nation.net/forum/elec...-schematics-07-08-canyon-colorado-w-3-7l.html

Use the schematics for Interior Lights Instrument Illumination. There are several wires going to lights on the dash.

run it off the remote for the amp.

Where is the gauge mounted? If it's on or near the dash, one of the wires on the back of the hazard lights switch is the illumination wire. I forget which color.

oh i thought u meant a voltmeter for the sub/amp feed...lol well then run it from a footwell power, they're always hot.

The light?

Is it a switched source? Otherwise the light will stay on all the time if it's a constant 12v+ source.

Not a very good idea at all,unless you want your remote on to burn out in your head unit and no longer work anymore.

why would a small draw do that? if it over shoots the amperage it'd blow the fuse. and the voltage wont change...it wont backfeed

because remote on from your head unit is not to be used for 12 volts constant draws it is a voltage signal just to let the amp know to turn on when the deck is powered on. You can blow a remote on just by using it to hook up too many amps to it it is recommended to use a relay for a turn on system with 3 or more amps.
quote from bcae
" Most remote outputs are switched through a very small transistor. This means that they are EASILY damaged by excessive current flow. They should be fused close to the head unit with a .5 amp fuse. A 1 amp fuse may not protect the switching transistor, which supplies power to the remote output. Do not try to use the remote output to power fans directly."

So even if you used a 0.5 fuse to save your remote on circut I don't think you will power a 12 volt light without blowing that fuse instantly.

DB has a point, make sure its only feeding 12 volts when the key is on, otherwise you will wake up with a dead battery.
