Brief
This tutorial can be used to integrate a motorcycles turn signals into the rear brake and running lights. When the rider turns on his blinker, the corresponding lights will blink on the tail. The circuit will blink the running light and will also blink the brake light when the rider is braking. A power resistor is added so that the speed of the blink will not change. This tutorial assumes you have a motorcycle with two distinct sets of left and right tail and brake lights. Somebody with basic electrical skills should allow 2 hours for the install.

Tool List
Wire Cutter
Wire Stripper
Insulated Connector Crimper
Soldering Iron
Heat Gun or Lighter
Multimeter (optional)
Instructions
1. Disconnect the taillight wiring harness and remove the rear cowl to access the wires.
2. Locate the right turn signal harness, cut, and strip the wires.
3. Solder two lengths of wire to the ends of the power resistor. Use shrink tube to cover exposed wire.
4. Using a BLUE spade connectors, crimp one turn signal wire and one resistor wire into the connector. Repeat for the second set of wires.
5. Refer to your bikes wiring diagram or use a multimeter to identify the three wires coming from you right taillight. They should be: Brake +, Running +, and Common -.
6. Cut and strip the Common (-) wire and crimp on the RED spade connectors.
7. Cut and strip the Brake (+) wire. Slide a piece of shrink tube over one of the wires. Solder a diode into the line noting its orientation on the wiring diagram ( bar end faces lightbulb ). Use shrink tube to cover exposed wire. NOTE: Ignore this step if your brake light and running light are made of LED’s.
8. Connect the turn signal connectors to coil terminals 85 / 86 on the relay.
9. Connect the taillight Common (-) connectors to NC terminals 30 /87a on the relay.
10. Repeat steps 2 to 9 for the Left Side.
Congratulations, You’re Done!
