i need to know which wires will give me a signal for the following sensors
knock sensor and TPS...
also where in the engine bay can i get the rpm feed from? isnt there a wire that goes from the ecu to the coil?
as for the TPS, as i understand it it measures the angle of throttle input, ie between 0-100% this angle of opening is fed back to the ecu in a voltage form?
so say if the throttle is 25% open it will give x amount volts and if its 95% open it will give a value different to the one that of 25% opening??
