How to Wire a Trailer Break Away Switch
- 1). Run the black, white and blue wires from the breakaway control box to the trailer's tongue.
- 2). Connect the black wire to the trailer harness' red wire with a scotch lock connector. These work by placing one wire in each slot and closing the gate. This forces a metal blade into each wire creating a connection.
- 3). Connect the white wire from the breakaway box to the white wire on the trailer harness with a scotch lock connector.
- 4). Connect the blue wire from the breakaway box to the blue wire on the breakaway switch with a scotch lock connector.
- 5). Connect the other blue wire from the breakaway switch to the blue wire on the trailer's harness with a scotch lock connector.
- 6). Wrap each connection in electrical tape and secure the loose wires with cable ties.
