I picked up a VW drive-by-wire throttle pedal. This pedal is compatible with my Simovert and fits the car better than the Zilla Hall Effect Pedal. The equivalent circuit is complicated, I've measured the resistances and the behaviour of the voltage dividers so it should be possible to deduce. I guess the VW engineers are sanity checking the voltage of the output against the resistance of the divider.

I need to identify and acquire a plug to match the socket on the pedal. Does anyone know what it is?
