Spark A to Cylinder 1, green
Spark B to Cylinder 3, brown
Spark C to Cylinder 4, white
Spark D to Cylinder 2, yellow
Right now I have the ms3 running wasted spark with my fab9 COP PNP setup. It looks like cylinders 1 and 3 can stay connected thru the oe harness, and I'll just have to cut and run spark c to white/#4 wire, and spark d to the yellow/#2 wire that go to the igniter, and set the ignition setting to COP? Is that all?

Sounds right. When you take apart the OEM harness it is pretty obvious how they are connected. Just make sure you cut the connection to cylinders 2 and 4 after they split off from the main harness. If that makes sense.

The oem harness (4 wire connector side) plugs in to the fab9 pnp harness. I have to cut off cyl 2 and 4 from the fab harness. The oem side of the harness shouldn't need to be tampered with since I'm not using the section that splits to the 2 coil connectors.
