Installation Notes and Tips

Verify the vehicle uses a 3-blade terminal electronic flasher before ordering. Match the connector gender, terminal count, and voltage specification to the original unit for proper operation. On many applications, the flasher is located in the fuse or relay panel area, but exact placement varies by vehicle.
