Wiring help

Can anyone help identify what these wires go to? 71 F100 and this is the main dash harness in the area behind/under the instrument cluster. I have two solid brown wires that terminate into a female butt connector. Also have two green with yellow tracer wires that terminate into a female butt connector. One solid orange wire going to a male bullet connector. These are all OEM style bullet connectors.

This is a quick reference for 1972 trucks. I dont see why it would be much different if not the same. This drawing shows wire colors as well. With this drawing you would need to verify where your wires originate and terminate. Im no electrician but I see tracing wires in your near future.

Unless I'm missing it, I can't find anything showing 2 green/yellow wires going into a bullet connector?

Maybe 54A? ...coming off the 'lighting switch' connector. It appears to terminate with your bullet connector but going to nothing. If you follow it back it looks like the same connection as 54 which goes back to the fuse box.
54 and 54A are listed as Green/yellow stripe in the color code list.
Not sure if it's the same for 71, but in my 69 the green/yellow wires go to the door switches for the dome light.

My guess, without looking at my old harnesses is that it's for the stereo power and backlighting, or for the heater.

Just commenting in the orange wire only...on my '69 the unconnected orange wire in that exact location was to the auxiliary fuel tank sender. It's in the posted diagram just to the left of the Brake Warning Lamp Switch.
