Looked over your lonk, Thank you, now I have an idea how that works.
How about the coil side? It looks like you just unscrew the end of the lead from the coil, but I haven't seen anything that says they are removeable. A picture?
That's right, the cap unscrews and there's a couple pieces near the end of the wire, works almost like a compression fitting. OEM wires are 7mm so if you use that size you won't have to trim the ends to fit in the caps. Likewise, using 7mm makes it easier to remove/install the new wires in the rubber boots. The trick there is to use plenty of alcohol to lube it. They'll slip right off/on, the alky evaporates and doesn't leave a residue. The OEM wires are solid stranded so I used the same thing.
