Special relay harness designed to disable power to your LIND laptop charger when the motorcycle ignition is OFF. Enables charging the laptop battery when motorcycle is running, but shuts-off 50 seconds after ignition OFF via SPST relay. Due to varied locations for LIND chargers, unit comes with long wire leads and an adhesive cable tie base to mount relay where most convenient. Note that without this relay harness, each and every time the motor is turned-OFF, the LIND charger will remain ON for 30 minutes, draining the auxiliary battery. Reducing parasitic load extends the life of the auxiliary battery!
