Question ST170 Coil Wires
There are three wires coming from the coil on my Mk1 Focus ST170 engine (running standard fuel injection with a Megasquirt ECU) sitting in my MK Indy R:

Orange and black
Green and blue
Green and black

Does anyone know what purpose in life these all have?

Thanks in advance,

Elvis
