Having hell with the wiring. So yeah, I installed the under dash gauges, then noticed I had a blown fuse on the panel lights. Replaced it, had lights for a while, then didn’t again, but no blown fuse. Reached up under the dash and started jiggling the headlight switch and could’ve sworn the lights flickered so I replaced the headlight switch. Still no work. Went to work under the dash with a schematic. Orange wire comes off of the fuse panel, hit the headlight switch. Comes off the headlight switch and goes to the brake light switch. The orange wire at the headlight switch makes the Brown wire to the tail lights hot, and the green wire back to the fuse for the panel lights hot. From there a gray wire comes off and goes to the dash lights. For the longest time I did have orange power at the headlight switch and then I didn’t.
The red wire at the headlight switch 12 V hot, only feeds the headlights. They have worked the whole time. The problem is with the orange. I finally moved some wires on the back of the fuse panel and realized the orange and the purple had worn on each other so badly they were almost worn through. Repaired them, and now I have tail lights and dash lights. However, when I press the brake pedal, tail lights go out.
Ground issue?
