Installation is easy. With the wires attached to the spark plugs, they are run through whatever wire looms or clamps you have, up to the distributor. Once the length of each new wire is determined, they can be trimmed and the new caps installed. This is done by first sliding the rubber boot onto the wire (a little silicone lubricant will help), then stripping back 1/2 inch of insulation to expose the conductor core. This is folded back along the wire as shown, and a spark plug wire crimp tool used to crimp the terminal in place. The boot can then be pulled back over the terminal. Once all the leads are installed, you can set the timing as required for your engine, and you're back on the road.
