Connecting the Heading Sensor to Power
When connecting the power cable, do not remove the inline fuse holder. To prevent the possibility of personal injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. Connecting the power cable without the appropriate fuse in place voids the product warranty.
You should connect the red wire to the power source through the ignition or another manual switch to turn the device on and off with other electronics to avoid battery drain.
