Installation Notes and Tips

When installing the Standard Ignition RY-859 relay, ensure the vehicle’s ignition is off and the battery is disconnected to prevent electrical shorts. Verify the relay’s connector matches the vehicle’s wiring harness, noting the female square connector and four male blade terminals. Since the relay does not include a mounting bracket, secure it firmly in place using existing mounting points or appropriate hardware to avoid vibration or movement during vehicle operation.
