I have two questions that I'm sure some of you guys can answer easily. My 1971 Ford 2000 did not have any headlights when I bought it. Also the switch on the dash that I assume worked the headlights is frozen up. This fall when I start to restore my tractor, I want to put in the proper grille that has the openings for the headlights and then new headlights. I also want to install a work light at the back of the tractor. Question #1: Do I need to install a relay with the headlights or just wire them to a new switch. Question #2: Does anyone happen to have a wiring diagram on this tractor that you could post on here. My tachometer and hour gauge are not working either, and if I could look at how they are supposed to be wired, I might figure out the problem. Thanks in advance for your help.
