The rubber bootie on the aux coil. The coil wires - white-black is ground, while the solid white is positive. While you have an opportunity, thoroughly clean the contacts on the aux coil, as well as the wires. If your coil is suspect, now is a great time to think about installing a replacement, since it'll never be easier to get to than right now.

The aux coil wires run through the radiator crossover plate. After disconnecting them from the aux coil, and probably clipping a wiretie or two, simply route them back through the grommet and out of the way.
