A31 Ecu Wiring

[Alkemist]

I have found a couple of rb20det ecu pinouts online but they have conflicting information. Does anyone have a definate A31 Rb20det ECU pinout.

Alternately, does anyone know which wire is needed to connect an external 'digital speed measuring device'?

To me it looked like there may be two wires to each pin, +/-. If this is the case, how is it possible to connect the device to the ecu, if the device only has 1 wire available.

Any info would be appreciated, thanks.

Perfect mate exactly what I needed, Yellow/Green it is... however, how do I wire up the sensor?

It has just 1 wire thats needs to attach to the ecu. I wired it up to the Yellow/Green one, but nothing happens, car works fine, speedo etc all work but not the device? Any ideas?
