Tim- thanks for the tips. L goes to the turn signal lever, but P ?? The wiring diagram for my steering column (actually for the whole 67-72 truck) shows two leads coming from the curved connector for each of the front turn signals. One goes to the front light, and the other goes to the indicator light on the dash (light blue to right and dark blue to left). Do I splice two wires together from P terminal, and if so, how are they connected to the two indicator lights so they flash correctly?? It just occurred to me that perhaps I should have only a two prong flasher for this set-up. That is what is shown on a diagram from 50chevy.freeservers.
