Hello and welcome to RamForumZ, glad to have you here! Sorry to hear about your problems! Sounds like some wires crossed somewhere. I know on my '81, if I lost my dash lights, the running lights were out (only had half a tag light anyway which the fuzz was not a fan of, lol, so I know what you mean about having to drive at night), but have you checked just to make sure everything is wired correctly? Just a thought until someone with more electrical knowledge than myself can answer your question, but in the meantime, good luck with that and keep us posted, but any other help you need, just ask and I hope you enjoy the board!
