No not really. Most of the wiring is redundant anyway. I just determined what was what, trimmed out the unwanted ones (there are a lot of earth connections that go back to one main earth) and sealed of the ends with small shrink wrap. Then made up a new front loom to accommodate the battery, switch and capacitor. Now there is just one multi pin, waterproof, Deutsche connector linking everything to the main loom. I am surprised that OSSA use only one loom. It would make sense to have a simplified version when the bikes are being exported to countries where registration and on road use is not a option? Maybe what they should do is create a loom that is able to accommodate the inclusion of a battery and then perhaps include the battery??? But then I guess there is no need as it is just the odd bike that wont start huh!!!!
