well, just to close out this thread, I took off the side cover today to re-inspect those field coil wires. They both looked black and are cloth covered, but when I cleaned them up with butane, they are indeed green and white, and I actually had them right anyway! So, it may not matter, but probably does matter since, they ARE colour coded.  Thanks guys. Fingers crossed, the K0 is almost done and I'll try and start it this week.

Ok, I better look again then. It sorta seems that if the wires that they plug into are green and white, they must need to match up. The 3 stator wires are all yellow on either side of the connections, so it makes sense they don't matter. I'll get out the microscope
Thanks guys

No, sorry Mark, that's the stator wires (yellow). The field coil has only 2 wires, and they go to Green and White. But there's no matching color on those wires, so I'm assuming, like the yellow wires, it doesn't matter. I'm just trying to make sure before I start it up. Thanks

Thanks, I've messaged him, but have not heard back yet, to ask if he would ship to Canada. I may take you up on that offer! Thanks, John.

Thanks KP. I wondering though, how did you find this part? on an Australian eBay, from an Italian seller? Do I need to set some preferences different on my eBay to see more stuff from around the world? Thanks, John.

Thanks guys, John.
