Well I got bored today and here are the results...
Initial Starting point was a "HP Coil and Wire"...
Yes, I pulled this apart. I think it would have been easier to just "unscrew" the wire.
Kinda difficult to describe what attaches to the wire but it feels like a pin screw when putting the wire in.
Mine had some sort of heat shrink that I had to cut off before unplugging this portion.
A little clearer picture of the "pin screw" inside the coil end of the plug.
Yes, I have an issue with using calipers and or micrometers for everything. It's 7mm wire.
Screwed plug onto wire, checked for continuity, placed heat shrink on.
This is 7mm Beltran wire from the local NAPA. Once the coil end goes on check again from one end to the other. Green or Black lead to plug end is around 1.75. All buttoned up.
