Hey!
I'm setting up my VEMS wiring and I have few issues.I want to use original VR sensor but it has 3 wires.
Looks like that.Car is VW R32 3.2 engine.Sensor is BOSCH.

One of the wires (pin) is cable shielding and its not connected to anything, just wrapped around other two cables. You can use this sensor for vems...
