Looking for a power supply for a digital gauge that comes on only when the ignition is on. I found several threads saying for the 05-07's it a red wire with light green tracer. Is the wire color the same for the '08's. Thanks in advance.

I taped into the 12v wire that goes back to the trailer plug. You can unwrap the plastic wire loom under the truck that runs along the frame rail the entire length of the truck. Its a big gauge wire that is fused so it gives you a good 12v source to tap into. I have my radar detector hard wired to it. So when the truck is off so in the radar and when I turn the truck on its on. I also used it for the power wire for my gauges and I also ran a wire from the trailer running lights up to my gauges so the backlight comes only when the lights are on.

I have not yet been under the truck to look at the loom (or the wires in it) but am planning on it as soon as I get my on board compressor and airbags.

My question is....Is it obvious which wire it is? What color is it? Or is it larger than the other wires in the loom thus making it obvious as to which one it is?

Thanks!

I think this question has been answered...
