My grandfather had his neighbor build this in the early 80s. It used to control all the driveway lights via a laser built into his drigeway columns. It also rang a bell the neighbor hand built in the hallway. It ran up until about 5 or 6 years ago, a man hit of of the columns and another person hit the pole at the end. Finally the buzzer went out.

The burnt red conector is wired to the same harness as the 4 pin transmission harness. The black plug is a 3 wire plug that has blue/green/red with white stripe.
