no dash lights

Im the first to admit IM not very good with electrical issues (lucky me, I have some). 64Ragtop, I will do what you suggest and see if that helps, I have not pulled the dash yet. I agree, the fuse holder looks nasty.
I know a guy who just parted out a 70 Valiant and if its not gone he had no use for the harness. Of course that is a different gauge panel than the one I have.
I guess my main fear is when I pull it apart I will end up with other problems. At least everything from the firewall forward works and I have running lights and tailights and it starts & runs. lol
