I thought that @g21-30 was pretty well-versed in the CDI wiring.

If you reference the DIY on Diagnosing problems with the CDI, you would have seen the diagram that is attached.

With the following info taken from the DIY, your question is answered:
========================================================
After removing the original CDI and disconnecting the original wiring harness, I then used a razor knife and carefully sliced down the center of the harness and peeled back the electrical tape. This exposed the eight wires; however, only 7 will be re-used, since the '88-94 CDI only has 7 connections!!

Next it was just a matter of connecting 6 matching pairs of colored wires. The one remaining wire pair (solid Red ['88] and Brown with black stripe ['08+]) were then connected. Just to show how confident I was that this was going to work, I didn't bother disconnecting the battery. Just make sure the Red and Br/Bk are the last wires connected and DON'T let the plyers touch the frame.

=========================================================
