My initial thoughts involve a piece of wood and a couple of finishing nails driven in and bent over to get the heads 7/16" apart. Then could I just take a piece of wire from the plug boot to a nail and a wire from the other nail back to the block?? I'm wondering what your rig looks like. Seems too simple to work, so I thought I'd ask...
