Hi this is Al, If you are using the wires under the steering column you are trying to use the body builder wiring not the up fitter switches. The up fitter wires are near the center of the dash behind the radio and heater controls. Here is the wiring diagram. Please note 2 are 30 amp 1 is 10 amp and 1 is 15 amp. Make sure to use the right one for the device being hooked up. I hope this helps, if not let me know, Al

There are no exposed wires out of any loom in that location. So, I am right where I started. Any other advice?
We went in a circle. That is the wiring I said in the first instance that none of the color coding matches the switch coding. And they don't.
Where are the upfitter switch wires?
