When I got my 71 Mach1, most of the wiring was butchered, including the original terminals in the grill/headlight area. Only thing connected was the headlights. I'm installing a Painless 21 circuit harness and I can't remember how all of the front lights work. I'm trying to remember if the lights in the grill come on when the headlights are on, or if they are paired with the parking lights and the side marker lights. Also, are the side marker lights paired with the bright or dim side of the parking/blinker circuit? Any help would be appreciated. It's been 38 years since I sold my last 71 and my memory ain't what it used to be.
