P38A Thor/Bosch engine RPM signal

OK i'm stuck with my new LPG ECU anyone know where I can get an RPM signal from the thor engine? I can't find anything useful in RAVE and theres no rpm signal or similar at the bosch ecu.
Pin 32 on connector 3 is 'crankshaft sensor', do I splice into that? pin 45 is Crankshaft sensor screen - ground and pin 46 is Crankshaft sensor signal - ground

It's ok.. I'm being stupid as usual! While looking for something else, I noticed connector 4, pin 17 - engine speed output derr

Tell you what, this is a wild stab in the dark but have you tried pin 17 on connector 4?!
