Hey there and thanks in advance for your input. My 67 is not an RS, just a sport coupe. Headlights, tail lights and brakes all light correctly with my switch. My issue is the dash. To begin with I confirmed power from the fuse panel.... except that the instrument fuse will only show power when the dimmer is dialed all the way.... even if the Headlight switch is pulled to turn on the lights, the instrument fuse shows no power on either side of the fuse unless the dimmer is dialed out, to illuminatethe dash (which it doesn't). Furthermore the dash lights don't even come on at all. When I dial up the dimmer switch only the turn signal dash lights illuminate. The dimmer switch won't even turn on the dome light, when dialed all the way. I am truly hoping someone here has some previous experience with this that could help. Thanks again.
