Your spark plug wiring shouldn't make any difference as Harley uses a dual fire ignition system. The spark plugs both fire at the same time so it doesn't make any difference which wire goes to the front or back cylinder. This is correct unless someone has changed the ignition system on the bike. However, if you will contact me directly at [email protected] , I will scan a copy of a domestic schematic and send it to you. I do not have access to European wiring diagrams but they should be the same as far as the ignition circuit goes. Don't forget to remind me of what you need.
Good Luck
