WARNING
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or
product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product
specifications. In addition, 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.
1 Route the power cable between the power source and the device.

(+) battery terminal if necessary.
