68 how do you keep the parking lights on with the headlights

I guess that I would have to try it to believe that parking light wouldent feed the headlights when you have the switch in the parking light position

Maybe if the switch has a terminal for parking lights and a terminal for tail lights you could (at the switch) unhook the parking light terminal and connect it in line with the tail light terminal that would add the 2 front parking lights???

The headlight power is a different crcuit - it is fed by the headlight terminal on the switch - the parking lights are powered by a "switched" terminal, and the tails are powerd by their own terminal. If the tails and parking lights are jumped, it wont affect the heads because the heads are powered by their own terminal that is not connected.
