I have signal lights and brake lights but both do not work when I push headlight switch to on position, or even just push parklight rocker to on. Have replaced the rocker headlight switch. Do not have a wiring diagragram. Was hoping this was an easy fix. Hope you can help me out.
have not done any extra wiring problem just showed up on weekend.

This is typical of a broken ground wire at the rear lights. You will find the two brake lights are not as bright as the signal lights, and if you try to run the left signals, the left rear bulb will not light up if you remove the right rear bulb.
