Starting from scratch

[Riverbum]

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.

The 71-72 grill lights are paired to the headlights.

71 wiring diagrams are in the Wiki section

Like CC said, the sport lamps from the factory would only illuminate with the headlamps on. How you wire it is up to you.

Side marker lights are wired to the running lights. They do not blink with the turn signals.

I remembered that, but I couldn't remember about the grill lights.. When I put power to the original plug I found for the turn signals, the bright side of the 1157 on the turn signal came on with the side marker light. I swapped that up. Appreciate all the help here

Way back in the '70's, I rewired the grill lights on my '72 Mach 1 to come on with the parking lights. I just liked the look better for cruising around in the early evenings.
