If you plan to swap your coil or do the swap mod on your Excalibur then more than likely you will need the proper wiring chart. Of course a quick search will find you several charts very similar and one that was technically wrong on one of the coil wires. The chart you will commonly see by Davespen has been updated with more info and is available to download here for free.
This chart was updated last year in 2020 and can be downloaded here in the zip with the JPG and Excel file. Please use this moving forward and share freely.
