Front is done....now on to the rear!

Just finished installing an ECE 2 1/2" drop spindle disc brake kit with 1" drop springs. Now it is time for the rear. Really trying to figure out what the toggle switch was for (hole above the ignition). Traced the wires to the dash speaker and radio but they did not work. Wondering why it would be on a toggle switch? I saw at least 1 truck pic on this site with the same setup. Any thoughts? I do not think it was to switch between dash speaker and speaker outside of truck but who knows...
