They are off the ignition. Just to double check, the yellow is the constant hot, the red/white is the switched source, and brown is the ground??

I was wondering what the yellow and red/white are rated for. I want to hook up 5 gauges to them, or what are some other wires I could use??

 

that wire you tapped looks like a 12-14 gauge
if you want anything bigger you need a hot lead from the battery

 

12-14 gauge wouldn't fit into a blue butt connector. You're looking at 18 gauge.

And that's an awful messy wiring job. I'd re-splice all those wires back to stock and leave them alone. The ignition switch is a discrete circuit... which means its only rated for about 2 Amps.

You'd be better off tapping into a power window circuit which runs out of the Body Control module towards the front of the center console. That way your gauges will be on a switched ignition source rated to 30 amps and you'll have nothing to worry about.

Here's how to find that circuit. Remove the fuse panel cover from the right of your center console. It'll just pull off. There will be a big red connector with a screw in the middle of it. That's your connector. Just above and to the right of the screw you'll see two Dark Green wires coming out. Those are the power window switch outputs. Use a test light to verify that they're hot only in accessory and run and you'll know you have the right circuits. Now just tap in with a scotch lock and install a fuse holder with a 5 or 10 amp fuse in-line on the power wire to your gauges and you're set.

That's how I got my turn on signal for my aftermarket stereo. Managed to keep RAP that way.

 

You should have seen it before I pulled out all the wires, the guy before me really did a number. What I am going to do is run a new power wire from the fuse box. What is the brown wire, is that a second switched or constant hot?? I cant check it because I am working on bigger wire to the battery and its not done yet..

 

brown is ground

 

Its hard to tell what that brown wire is without a pinout or knowing what its plugged in to.

It would not be safe to assume its a ground though. It could be a signal circuit to the BCM from the ignition switch.

If you're looking for a good ground, anything bolted to the metal dash carrier would supply a good ground for low amperage circuits.

 

hey go right to the tumbler / Key / Ignition...I am going to run a new hot from the fuse box, and find a new switched source, like the one for the radio

 

The switched source I mentioned coming out of the back of the BCM for the power windows will work for your purposes.
