Interlock Safety Switch

Thanks for everybody's help. I got it working right! I kept tracing the wires from the relay. The ground wire was put on the ignition lead at the relay and a jumper wire went from the ignition lead on the relay to the bulkhead connector where the transmission harness goes. The previous owner did this. I undid the crap and got the transmission harness in. I have backup lights and it only starts in park and neutral now.
