Sluggo,
I have not tried the Hysol technique, but it sounds good. When I made my multiplex plug for the battery/ECU connection I used the bent the wires as others hve described as a 'wigwam', put shrink wrap on the wires and then 'painted' the multiplex plug and wires with liguid electrical tape from Home Depot. I'll post a pic when I get home this evening. If you put a wrap of electrical tape on the plug and about 3/4 inch down the wires, then apply the liquid tape, it makes a nice appearance, further insulation between wires and relieves stress on the solder joint in the plug. For what it's worth from one fighter pilot to another!
Regards,
Gus
