The wiring to the D2’s coil pack is a 3 wires plug. The middle one is the 12v supply, but can someone explain to me what are the other 2 wires?
Thanks,
Ed
The "Discovery Series II 2000MY Electrical Circuit Diagrams - 2nd Edition" page 20.4 shows them as wires going straight to the ECU. Probably trigger voltage for each of the two spark generators in each module.
Yeah, ground paths to the ECU for each of the two pairs in the wasted-spark system. Power in through the middle, with the ECU giving a path to ground to complete the circuit.
