Any pressure sensor which produces a linear 0-5V output may be used as an analog input on the S300.
As an example, here is how to wire the Autometer 0-100 psi liquid pressure sensor.
You will need both the sensor part # 2246 (4590-0023-12), and the wiring harness, part number 5227.
The sensor harness has three wires:
| • | +5V (grey) - connects to an ECU 5V voltage supply |
| • | Ground (black) - connects to an logic ground |
| • | Signal (purple) - connects to the analog input |
eg. Connecting two Autometer pressure sensors.
Be careful! The logic ground pins A26 & B2 are next to +12V pins, which will damage the S300 / sensor if connected by mistake.
