Is the bulb test module involved in the brake light ckt? I installed new switches on the master cylinder and tested continuity from the switch plug to the brake lights and all good but not working when pressing the pedal. The car is 1978. Hair pulling problem! Thanks for any suggestions ahead of time

If the module is disconnected , the brake lights will not function.
