Lights
Ok, heres my problem. This truck I got has been sitting for a few years. None of the bulbs really worked, so i replaced them all, and the flasher. I still am not getting any passenger side light (execpt for headlights), and my flashers on the drivers side dont work either. Now, going through my manual, im trying to reach a starting point, and from what I can tell, all of the Illumination lamps get their power from the throttle actuator? Thats where i can trace everything back to. Is this right?

What year truck are you working on?
On most vehicles, the headlamps and the marker lamps originate from the headlamp switch. Even though they go to a common switch, they have different power sources or feeds to each. The headlamp switch also includes a seperate feed for the instrument lights.
The turnsignal lighting has a power feed to the flasher, and then goes to the turnsignal switch where it's routed to the brake lights in the back, and the turnsignal/marker lights up front.
