Temp Wiring Zetec

Evening all

A nice easy one I hope,

Just trying to connect my blacktop temp sensor to megajolt and temp gauge.

Two sensors, the top I believe is for the ecu, bottom to the dash.

Each have two wires, I assume a sensor and earth, however is there an easy check to see which is which?

Tried trial and error to the gauge but neither combo did anything, am I right in saying the gauge gets power, earthed and the the sensor wire - With the other wire from the sensor going to earth?

thanks

Simon

Temperature sensor / variable resistor

By default the MJLJ is optioned to accept an input from a thermistor type temperature sensor, reflecting the most common usage scenario: correcting ignition advance based on engine temperature during warm-up.
