CB Radio install. Help needed.

[Coloradaho]

Where are you guys pulling power from for your CB Radios? Any info and PICS would be very helpfull.
I am planning on doing an in dash mount under a single din head unit in the stock dual din opening.
I have three wires...
Constant power
Key "on" power
and Ground

[Acidsniper]

Constant power you can run to the + battery terminal
Key "on" power you can piggy back off of another wire from the fuse panel (radio wire works best, usually)
Ground can be grounded anywhere as long as it's bare metal. Look for where your radio is grounded or ground it directly to the firewall (don't forget to grind out the paint to bare metal first)

I'm totally new to working on newer trucks. Meaning, I've had this truck since it was new and haven't done anything to it myself until now. I am clueless as to what wires go to what and even penetrating the firewall. I can see where a big bundle goes through behind the fuse box, but have no idea as how to pass a wire through that sealed off unit.
How do hook up to the "hot" stereo wire? Pull the fuse box and solder wire to something? I hate cutting into anything and possibly damaging something I don't know how to fix.
I can handle the black wire, but that's pretty cut n dry.
Pardon my ignorance in this matter, but if it ain't got a wiring harness I can just plug in to, then I'm in need of the guidance from someone more experienced with such things.

Use some splice connectors, mine is hooked up to something coming out of the column.

I pulled two wires from the battery and fused both. ( for da ham radio) you will pick up less noise on the RX side. You may also want to conside a cheap inline noise filter. Mount the antenna any place other than on the bed next to the cab corner and any SWR less than 2:1 is OK.
