Connecting the three wires on the power cable of my MEGA 360.
You must connect the drain/shield wire and the ground wire on the MEGA 360 power cable to a ground terminal/boat chassis ground point to ensure good performance.
The drain wire is the non-tinned wire. If this wire is not visible, it is necessary to strip the outer casing of power cable by two inches in order to expose the drain wire properly.
See the MEGA 360 Installation Manual for full installation instructions.
