Logical answer to Right side tail light problems
Just bought a 1999 f-250. Gently easing it back to normal. One niggle has popped up. Right rear tail light brake at first was intermittent along with the high mount brake lamp. Now it will not show brake. It will show running light, it will not show signal. The bulb is good. The socket is good Disconnecting at the connector near the left wheel and testing with a probe light I find blinking on only one wire. The power is not coming from the front of the truck to feed right side. The fire wire at the right rear is orange with a blue tracer. Next: Probing under the hood under the air intake I find an orange wire with a blue trace. Test light produces flash when the right signal is on. Therefore orange-blue wire is hot under the hood but not at the connector. Is there anywhere to look for a wiring diagram for the drop nosed f-150/250

Ok I think I got it nowwwww
When I signal to the right nothing happens at the rear of the truck until I move the tilt wheel up and down. Therefore the problem, I have learned through hours and hours of reading, is in the steering column Multi Function Switch. No need to pull steering wheel. Just to find the part for less than 100 bucks.
