WTR –

This is the ground reference used for two-wire water temp sensors. This will connect to one of the wires from the Dakota Digital SEN-04-5. The other wire will connect to the WTR SND terminal, and it doesn’t matter which wire goes into either location.

OIL +

This terminal is used to supply power to Dakota Digital pressure sensor SEN-03-8. This supplies 5V DC to the sensor and should not be connected to anything else. Connect the red wire from the SEN-03-8 to this terminal.

***DO NOT use this terminal to power any other devices it is a low current +5V output.

OIL SND

The oil pressure sender included with this system must be used. Other senders will cause incorrect readings or damage to the control box.

The supplied sensor, Dakota Digital SEN-03-8, is a 0-100 psi solid state pressure sensor. The sender can mount on the engine block or in an oil pressure line off of the block. The sender has 1/8” NPT threads. Adaptor bushings may be used to adapt it for various applications.

The oil pressure sensor has three wires coming from the harness, plus one bare shield wire. The WHITE wire will connect to the OIL SND terminal, the RED to OIL + (5V DC), and the black and bare shield wire to OIL –. Do not route the oil sender wire alongside a spark plug wire or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge readings.

If the oil pressure drops below an adjustable warning point, the reading will flash as a low oil pressure warning. The default warning point is 10 psi. If the oil display shows “—“ this indicates that the control box is sensing a short to ground or out-of-range error from the sender or sender wire. If the oil display shows “EEE” this indicates that the control box is sensing an open circuit or out-of-range error from the sender. If either indication remains on the display, inspect the sender wire for damage, check the routing of the sender wire, check the sending unit grounding, and check that the correct sending unit is connected.

OIL –

This is the ground reference used for three-wire pressure sensor. This will connect to the black wire as well as the bare silver shield wire from the Dakota Digital SEN-03-8.

***The bare wire is the shield wire, connect this wire to the OIL – along with the black wire

***DO NOT connect this terminal to any other devices

FUEL +

This output is not typically used. It is a low current +12V supply for powering solid state fuel sensors. Currently, it does not have an application for any Dakota Digital fuel level sensors.

***This terminal should not be used with a typical resistive type fuel sensor. For most applications, leave this terminal open. Do not try to power other devices from this terminal or damage to the control box will occur.
