What I have done is to take 7MM solid core ignition wire...buy about 15 feet from a lawn mower repair shop...they should have the correct spark plug ends you need as well as the ends for the cap end of the wire...that end is a little brass deal that, when laid out flat, has a round flat middle with a little spike sticking up...this part goes into the end of the wire and the spike into the core...and there is a rectangular tab on 2 sides of the circle that get folded up the sides of the wire and have little spikes on them to grip into the insulation on the sides of the wire. Then I bought some boots for the 2 ends and put it together with civvy plugs. When inserting the wires into the cap end, through the mil cover, you have to be careful to put them in all the way to the bottom but not push to hard as you can crack/break part of the terminal tower that the wire goes down through...I did it on a brand new cap once...sucked...
Anyway, this is not water proof...it is better than the worn out mil wires that were on my truck, cheaper, readily available pieces, cheap enough to carry a few spare ends and feet of wire so any wire could be made if needed, and allowed for a timing light to be hooked up whenever...now that I run a civvy distributor, its moot to me...
It is a good way for guys using the military distributor to have a fairly easy way to check the timing...take off #1 wire and plug and put on this type wire and a civvy plug and hook up the timing light...for that application, its not something that would wear out any time soon...just a thought.
I do seem to remember someone sending me something on a way to use the civvy plug wires AND be waterproof...doesnt seem to be on the PC so I'm guessing it may be in a box somewhere...will search around for it...I found a box of RC plane stuff stuck in my truck parts in the shop yesterday when my daughters were helping me look for the horn buttons...
