There are a couple of different circuits going in, and a number of wires going out. Some outputs are hot only in the accessory position, some only in run, some in both, and one only in the crank position. In addition, there is usually one wire that gets grounded in the crank position. That one turns on the red brake warning light as a bulb test.
