Help installing Ultima 53-644 digital ignition

I have a 1999 Ultra cycles softail with a 113" S&S motor in it. My old stock ultra cycles ignition failed and I am replacing with the Ultima 53-644.
I cut the harness just above the old module and have exposed 4 wires..white, red, back and green...saving the plug above. These wires from the module plug into the harness where there is a green/white and red/ and black/white. The white and red has 12volts with the key and run stop switch on. I have run this to the central positive on the coil. I am installing the single coil option. My old coil was a dual fire with only two posts and two wires.
Now from the Ultima module I have the wire harness with white, pink, violet, green and now what do I do. The instructions are a bit confusing to me? Thank you, John
