How do you put the metal ends on? Do you just put them on the out side of the wire or do you have to stip them down or something???

 

Just crimp the ends to the wires and slide the rubber part over. It takes time though, not an easy task. Take your time.

 

Order this crimp tool from MSD, its msd part number 3503 (at summit type in msd-3503).

You'll first want to strip the wire back about 3/8" to expose the core wire (the msd tool has this part worked out for you as well). Then fold it back on the wire so that it contacts the metal end on the side that is not crimped. Then use the msd crimper in a vise to collapse the open end of the metal end around the wire. This will ensure the best connection possible.

If you don't strip the wire the spark will have to jump from the end of the wire to the metal end and then jump again at the tip of the plug. This is not such a good idea.
