PCM 112 Important Information and Pinouts
Circuit is designed to read low resistance sensors, typically
between 0 and 200 ohms. Uses standard fuel tank sending
units.
Dedicated 5 V positive power supply for transom and hull
sensors. Maintains 5 V regardless of battery voltage
fluctuations.
12 V power supply from the battery, through the main power
relay (MPR) and through the PCM 112. The PCM controls
the MPR through pin AA2. This power is used for high
current actuators.
