Without any significant specifications from your post about the instruments and setup on your boat, the easiest way is to connect the positive lead to another instrument's power source - that is "piggy-backing" off the power supply of the other instrument and its circuit breaker. Try to pick one that has about the same power draw.

All my electronics are switched on from a single "instruments" breaker on the electrical panel. The power to each instrument is distributed from a fuse box (blue sea #5026), with each fuse sized to the instrument manufacturer's specification. A separate power cable runs to each device. The only exception is NMEA 2000 devices which are powered through the NMEA 2000 network backbone.

The garmin 441 has a setting for the "low voltage" limits, which turns off the unit,
when the voltage goes below the setting. Try measuring the voltage at the cig lighter outlet, then change the garmin's setting to something a few volts lower ie. 13.3 or so. that should keep the unit from shutting down.
