I hadn't done this yet, so I stripped the plastic tape off the wire loom, exposed the crimp brass, and used a 75-watt soldering iron to do the job. I noticed the crimp was wrapped-with red electrical tape, and then the black tape. So, I re-wrapped it like stock. First pic is the soldering. Second pic is what's to be unwrapped to expose the brass crimp, just-below the main fuse block which is part of the rear cylinders coil bracket and electrical components mount. This pic shows the brass crimp in its factory, unsoldered state, in the middle of the pic.
