Step 5: Mount the Switch

With wiring secured, fasten the switch in your chosen location. Follow these steps:

Use the provided mounting hardware to secure the switch.
If necessary, use electrical tape or heat shrink tubing to insulate the connections.
Ensure that the switch is easily accessible once installed.

Step 6: Reconnect the Battery

Once the switch is mounted and all connections are secure, you can proceed to reconnect the battery:

Attach the negative terminal back to the battery.
Ensure everything is tight and secure.

Step 7: Test the Switch

Before finishing the installation, it’s crucial to test the battery disconnect switch:

Turn the switch to the “off” position and observe if all vehicle electronics are powered down.
Switch it back to the “on” position to check if the vehicle starts normally.

If everything works correctly, congratulations! You’ve successfully installed your battery disconnect switch.
