Option Code 66S Upfitter switch 12V circuits 1-4 are load fused for 25A each and can be switched ON when the ignition is in RUN or START. Circuits 5 and 6 are load fused for 40A each and are user configurable for ON in RUN or START, or always ON.

Where did you pick up a ground near the fuse panel?

yeah, there is a ground closer to the firewall iirc - couldn't have been far from the fuse panel (cause I don't recall it being an issue)

Bump....... Happy Fathers Day to all Fathers and expected fathers!!!!!!.....I dont have upfitter switches.........the 7200 wireless Airlift compressor is fused at 15 amps.....so i would need to find a keyed unfused 12v source .....preferably under the hood if there is one (either side of the truck engine bay).
One last question....surely the bed is grounded to the frame. ??????????????
Thanks again

I found a bundle of blunt cut wires behind the passenger side kick panel under the dash labeled "PTO", I found a switched ignition wire in that bundle that I used for my mobile radio, 200 Watt Siren/Light Control box, and satellite radio power.

PTO Wires
Correct, no upfitter switches. No, just found the bundle and probed the blunt wires with my test light hoping I would get lucky. Didn't think to take any photos... Was just happy I didn't have to tie into any wires already being used for something else...
Very helpful! I'll have to do some probing around.
