Unfortunately i havent ever come in contact with a cossie so i cant be that much help.

However, things like the injector wire, will be an earth off any injector (as they permentantly have 12v)

RPM wire can be taken straight from the wire on your rev counter.

TPS wire could be found with a multimeter/or from a diagram.

As for speed sensor, if your car doesnt have a speed sensor on the gearbox u will have to fit one.

These wires are all mainly for the extra features, it will still operate as a basic controller for boost without all of them!
