These are very high quality and non-resistor wire for points ignition only. I did the cap, rotor, non resistor spark plugs, and wires at the same time on my F head 134. You do have to cut the wires to length and install one end including crimping the connection. It was easily done with pliers that I had. The kit came with extra fittings to attach 90 degree elbows on the spark plug side; I kept the straight spark plug boots that were preinstalled. I cut and made all the connections on the distributor cap side. A small amount of Dielectric grease was included in the kit to lube up the rubber boots. The wires themselves are really high quality. Better than expected. The important part is they are non resistor for points use only and supply better spark with points. They probably produce radio noise but I have no electronics in my Willys so I do not care. If you are running an electronic ignition you need resistor plugs and wires or you might have radio/electrical interference with your ignition. These non-resistor wires and plugs are the way to go for points though as they will provide the hottest spark you can get with that setup.
