I recently bought a NOS Delco Remy 1116507 ignition switch and I was hoping the group could lend me a hand in identifying the poles on the rear of the switch. I'm assuming the three poles are for battery, ignition, and starter, but I'm not seeing any markings indicating which pole is which. I have included three pictures of the bottom of the switch and I was hoping someone out there might be able to help me identify the poles by looking at the pictures.
