Sorry about this chaps. I am in the UK with a UK 73 240Z.

I have a pertronix that i need to fit to the car. I have 3 wires coming through to the original coil. Black and white, green and white, and a white with a thin black stripe. All the wiring diagrams I have seen show that I should have. 2 x black and white and one green and white. I have traced the white and black back to the ignition switch the green and white appears to go there as well. the other is yet to be traced.

I am a bit of a novice with the electrical stuff, my forte lays in mechanical things. if you can help me I would appreciate it. sorry about the repeat question..

Thanks in advance..

I have another question which I will post as well..

I'm not sure what your question is, Black from modile to coil -, red to the balast resistor, unplug wiring from points. 73 240Z US model. Hope that helped.
