I've welded a stud between the 2 connections on the + and the - (note they dont have the same size on the genuine coil) and then wrapped them with self amalgamating tape so I've used the genuine loom without modification.. Don't have picture but I guess is easy enough to understand..

tip of the day: use a flame thing (don't know the name) to heat the stud on a clamp put some welding on it and then weld it on the coil with an electric solder or you'll never make the solder to stay on the stud (do you see what I mean?)
