I have replaced all of the fuses under the dash and still have no power to the taillights, radio, hazards, or cigarette lighter. Any advice would be greatly appreciated.
Thanks,

Fixing this would really involve testing the connections and tracing the wiring through and checking all the earths. The cigar lighter may be just a burned out element. Tail lights could be the headlight switch. Also check the main connector/ multiplug from the indicator multi function switch. I have had issues there with my '69. Are the indicators themselves working? There is also a separate flasher for the hazard flashers as I remember. Electrics can drive you crazy! Perhaps an idea of what DOES work might help isolating things. Corrosion and dirty connections may also be part of the picture. There are a lot of people on this forum who are more skilled than I in sorting things out! Hope this helps!

I’d start at the light switch - check the connector see if you have voltage there, then work your way back. Have they ever worked? how wbout your ignition switch does it work and operate anything in the acc position? How about in run position…
All of the interior lights work, the buzzer works, headlights work and the brake lights work.
If your loom is anything like my 67 XR-7 I would clean the block connectors that are located in the trunk (left hand side) I did mine today and they were dirty as hell, used 800 grit paper on all the points(male & female) and sprayed the connectors before plugging back in. Also did the same on the reverse light connectors.
Make sure the bulbs are properly seated in the tail lights and sockets. I had poor light prior and now rear lights are as bright as ever.
