Well, the wire from the ignition switch is the wire that transmitts the signal to initiate a start. That one has to hook up to the solenoid. As for the other one, I don't know. Was it a ballast resistor bypass? That is the only other wire that I can think of that normally goes to a solenoid. You may have a few wires for always on accessories that run to the same terminal that you hook the battery up to.
