68 C10 wiring problems!

[cwhitlock]

I have a 68 c10 that I started working on about 2 months ago. I am having some really strange issues with the wiring and wanted to see if anyone had any suggestions short of a new wiring harness. I have checked all bulbs associated with the below issues.

- When you signal left or right, the front markers work normally, but the rear both blink together.

- The floor dimmer controls the headlights but they only work on one setting, I believe it to be the bright. When you dim, no lights at all.

- Neither the running lights nor the brake lights work.

- Gauge lights only come on when you depress the break.

- Dome light does not work.



1968 C10 SWB, with 1970 350 and 1972 power breaks and steering.
