67 Rally Sport, when i pull out the headlight switch to the parking lite position the front parking lites and the rear tailights and tag light up, this has just happened as at one time the rear park lites did work in conjunction with the front parking lites, any ideas, think its the headlight switch or is there a relay to be concerned and if so which one where
Thanks in advance for the help

[X(] i think we need some clarification here. i cant remember the exact layout of the taillight assemblies for that year( is there four bulbs, two inside for park lamps and two outside for brake??) theres a few possibilities that come to mind depending on the light configuration bad headlamp switch, brake light switch, and GROUNDS. ill try to find a wiring schematic to aid me to help you refresh me on the light layout if you could kurt
