76 2.0. My original turn signal relay recently stopped working. I purchased several aftermarket turn signal relays, and they all buzzed when the handbrake dash light went on. I tried a recommended fix of putting a resistor in parallel with the dash light. That had no effect, the relay still buzzed with the handbrake light on. Finally I just disconnected the positive hot lead wire going to the dash handbrake light from the flasher relay. The wire should be black with green and white stripes. Then I attached a full time positive hot lead from the relay board to that same now open terminal on the dash handbrake light. The red dash light goes on with the handbrake up, and the flasher relay is bypassed so there's no more buzzing. It makes no difference to me that the red dash light doesn't flash. I hated the flasher/signal relay buzzing and the dash light serves it's purpose when it's lit up, whether it's flashing or not. You can't possibly miss the red light when it's on and drive around with your handbrake up.
