Hi all
I've not had a coolant gauge since refitting my newly rebuilt engine.
I didn't junk it was sending a signal from the temp sensor but I've bought a code reader and it's sending to the ecu fine.
So fault is just between ecu and gauge.
What wires do i need to be checking from the ecu and is there a sender unit between it and the gauge?

93 Cooper spi.

Well, it appears to be a green/blue wire going from the ECU pin 5 (single connector) to the temp gauge. There is nothing else other than voltage stabiliser for it and the fuel gauge.
