Dash installation, cross-section view.
Caution:
You should read over the entire installation section before drilling
any holes in your vessel!
You can install this gauge in some other order if you prefer, but we rec-
ommend the installation sequence summarized below:
1. Determine the location for the gauge so you can plan how and where to
route the cables. This will help you make sure you have enough cable
length for the desired configuration.
2. Determine the location of your battery or other power connections,
along with the power cable route.
3. Determine the location for the alarm buzzer and its wire route.
4. If you want to turn on the gauge backlights whenever you turn on your
dashboard lights, locate your boat's dash light switch and determine how
to route the dash light wires to it.
6. Install transducer, connect power wires to the battery and route the
power/transducer cable to the gauge location.
7. Install the gauge, and connect the power/transducer cable.
8. Connect the buzzer wires and install the buzzer. If desired, connect the
dash light wires to the boat's dash light switch.
