BOTM LOSER Proudly Deplorable
If you look in aviation parts on eBay you can pick up connectors that have a stainless collar at the female side that snaps tight around the male side, you have to shrink wrap them every time but they hold tight. I have been looking at buying a whole harness off a modern street bike to rob all the little micro plug connectors from for the lock fit they have too.
I have a spare XL185 coil if you find the Yamaha doesn't fit the bill.
