i am just going from the top of my head some of these things can be different but the positive and negative wires at the pickup coil in the distributer have to be connected to the red and white wires at the ballas then you have to connect the pos and neg wired from the ballast directly to the battery. and the black and orange wires go to the blaster and from the blaster you connect the ignition wire to the distributer cap i hope this helps let me know if i was correct
