hey guys and gals..
im trying to wire a wolf 3d ecu into my track car and im stuck...
i need to know how the dizzy coil crank angle sensor are all connected.
i know where the wires go, but i need to know how it all talks. what tells what to fire and when.
i need to tell the new computer to trigger (crank or cam) also need to decipher the 7 wires on the dizzy.
Any help would be awesome. cheers in advance.

Have you looked at the service manual circuit diagrams? that may get you started. from what i see on the dizzy.

pin 1 is power from ignition switch
pin 2 is tach
pin 3 is the ECU power transistor trigger signal
pin 4 is earth for power transistor

I'm struggling to find the others, 5,6,7. Not very familiar with these type of cct diagrams. Is there 7 wires going to the dizzy?

5,6,7, are on a different diagram and are the TDC sensor

Pin 7 is gnd at the ECU pins 13,26 connector B-108m , not sure if that's the harness end or the ecu socket
Pin 5 is going to pin 88 on B-111m which appears to be the other connection to the ECU
pin 6 looks like it goes to the engine control relay pin 1 which are the relay contacts when closed will supply power to the TDC sensor

Again, I've never got down to this level in a car or ventured into mods.
