Finished the left mag coil wire this morning -- it took two hours. Actually, more like three. First we see preparation of the wire, showing how the shield of the mag wire is tapped out to the black wire using a RayChem solder sleeve.

Next we see the finished mag wire, with much heat shrink for strain relief.

Finally, the whole wire assembly is connected to the left mag's quick tab, and the black wire (wire shield) is connected to engine ground via the mag mounting bolt. The black mag wire has clear heat shrink to beef it up. A drop of blue threadlock was added to the bolt.
