Help with crane fireball wiring

Hey, i bought a 009 dizzy that already has a crane fireball pointless ignition kit installed. there are 3 wires, a black a white and a grey. i dunno where they do 🙁 does anyone know how to wire it up to the coil? im stumped at why there is no red 🙁

Those wires plug into the "magic box" which is the other half of the ignition.If you don't have the other half it wont work!!
