ignition push button start

[brianallmotor]

i have most of the wires sorted. there are four wires that i need help with. on the ignition cylinder (thingy you put the key into and turn the key) there are two center contacts. those two contacts on the center of the cylinder are closed circuit when in START.... attached to those two contacts are four wires, they lead to a four wire plug in the harness.

colors of the wires:
Green = Batt +
Black = GND
Red/Black = ????
Red/Yellow = ????

is this possibly the steering lock solenoid?
