Fireball Ignition system, wiring??

Alright everyone- I'm not getting any spark and I can't figure out which way I need to hook up the wiring harness to my coil/ ignition.

I removed the engine out of my 240z along with the coil/ ignition/ distributor. The motor came from a 1983 Datsun 280zx its an L28 (non-turbo) It has an electronic distributor not points. So I have an L28 motor from a 280zx going into a 75 280z/ I know its stupid pointless but I changed my mind about selling my 240z and ended up having to use the motor I have. Also, the L28 is now running a triple carb setup, not fuel injection. First question: Do I need to change the distributor to get spark? Or will the electronic distributor work? Second: How do I hook up the coil to the ignition? On the Fireball Ignition there is a red wire that goes to + on coil, a yellow goes to - on coil and a black wire goes to ground. Those are hooked up.

Which way do these wires go?

And anyone know what these two do? Is one a ground?

On my 76 280z

Blue wire to coil negative

Black/white to coil positive

A couple of wires are eliminated that hooked up to the ballast resistor on mine because I have a XR3000

If you have a XR700 you still need to use the ballast resistor. With an XR3000 you can eliminate the ballast resistor.

Look up your wiring diagram for your car and for the crane unit you have and you should be able to get it.

I have an XR700. I can't find wiring diagrams off the crane cams website anyone know where to look exactly? I really need to get this car out of the garage

What if I just forget about the fireball ignition? How do I get spark? Can't I just use the car's original ignition. I have the original distributor that came with the 75 but the shaft is too long, so can I remove the shaft out of the electronic distributor that came with the 240 and put it in the 75 distributor?

I figured out that the carb setup isn't going to work with the stock fuel injection harness, so I'm just going to put the stock injection back on the car. However, I did put the stroker motor in my 240z. And I took the distributor apart and can't remember how it goes back together. Anyone have a picture of an electronic (not points) distributor, or one with the fireball ignition setup in it?
