Drill a 5/8" (15.9 mm) hole in the dash for the power/transducer cable.
The best location for this hole is immediately under the gimbal bracket
location. This way, the bracket can be installed so that it covers the
hole, holds the cable in position and results in a neat installation. Some
customers, however, prefer to mount the bracket to the side of the cable
hole — it's a matter of personal preference. After drilling the hole, pass
the connector up through the hole from under the dash.
