A successful installation should start with careful planning, including determination of mounting location
for the CNX80, cable routing, and other required modifications. Once the mounting location has been
determined, prepare the mounting tube for installation. It may be easier to complete the wiring harness and
attach the connectors to rear connector plate before attaching it to the mounting tube.
Carefully plan which external devices will be connected to the CNX80 inputs.
