on my mpi you have:

+ve 12v fused
earth/-Ve
signal
illumination feed (if side or main are on, counter illuminates)



Now, you have 3 wires, and I'd say +ve, earth/-Ve and signal are pretty vital therefore i presume its not illuminated?

The schematic is for spi but still the same, so i guess its all the same wiring.

also appears as though the m10/ecu feed is simply a potential difference with respect to the 12V so any meter/guage should be easy to fit

these should help anyway

++++EDIT


looking at your 3 wires out, one is missing....this must be connection 2 on the schematic, so :

wire on its own is 12V

wire on opposite end is ECU feed

wire in between the two is earth
