Dennis the wiring diagram is below.
Here's some troubleshooting guidance:
start at the fuse box:
Insure fuses 1, 2, 5 & 6 arer all good and making good contact in their fuse sockets.
Turn the headlight rocker switch "on", and pull the turn signal stalk back towards the driver, check for power to fuses 5 & 6. Then push the turn signal stalk towards the dash board, check for power to fuses 1 & 2.
You should findings should be:
(1) All the fuses have power but the headlights don't work. Your Pantera has a wiring problem between the fuse box and the headlights OR a grounding problem at the headlights.
(2) One set of fuses has power, but the other set does not. Your Pantera has a bad dimmer/turn signal asssembly, or one of the two wires supplying the fuses is disconnected (gray or green with black stripe).
(3) None of the fuses has power. Your Pantera has a bad headlight rocker switch, a bad dimmer/turn signal assembly, a disconnected white or pink wire, or the gray & green with black stripe wire pair supplying the fuses is disconnected.
To further diagnose condition #3:
Expose the back of the headlight rocker switch, turn it to the "on" position, check for power at terminal 8.
(1) If there is power to terminal #8, then your Pantera has a bad dimmer/turn signal assembly, the white wire is disconnected or the gray & green with black stripe wire pair supplying the fuses is disconnected.
(2) If there is no power to terminal #8, then your Pantera has a bad headlight rocker switch, or the pink wire is disconnected.
