ABS Wiring info
I'm looking for some information on the signal that is sent to the Wabco ABS ECU from the engine ECU on TD5 & Puma 2.4.

I have read that it is an rpm at 2 pulses per revolution but can anyone confirm?

I have found info for the question above but it has also raised another query.

The description tells that the ECM provides the ABS ECU with a signal about engine torque, throttle and type, but in the wiring it just lists this connection as throttle pedal.

Can anyone offer any help on what signal is sent on the SP wire?
