Ground (-) for pin 9
Pins 9 or 10 with their respective Ground returns (11 or 13) can
be used.
Normally, pins 9 and 10 are fused at 20A in the car's fuse panel.
The advantage of using pin 10 is that the PPP only charges when
the ignition is on, so the car's battery doesn't drain when parking.
Pin 10 is a non-standard option on most car models, so please
verify it's available.
If connected to pin 9 be careful not to drain the car battery when
the engine is not running. Disconnect the trailer plug on longer
stops.
Most absorption type refrigerators use up to 10A. When the PPP
is added on the same circuit, the 20A fuse is not overloaded but
there is no available power for other loads. When other loads are
used, such as the water pump or lamps, the refrigerator must be
switched to gas power.
