I'm having trouble tracking down a wiring issue in my 74 cj5 with an original mostly unmolested wiring harness. So far I've cleaned all the grounds I can find, replaced a couple of bad fuses, and tightened up a few loose connections. I am not positive all of the following are related....... The symptoms: no taillights no blinkers power into and out of the brake light switch passenger brake light works with the pedal drivers side brake light does not hazards - both front and passenger rear blink, driver rear does not but is on driver brake light and license plate light come on and stay on with the key, regardless of the brake pedal or headlight switch position. In the past all the electrical problems I have had have been solved by cleaning up the ground connections, but no luck this time around. Any suggestions? Your guys are awesome!
