How Do I Hook Up My Reverse Lights

Short answer: On a column-shift automatic, the backup-light switch and the neutral-safety switch are combined in one housing. The purple wires are the neutral-safety circuit; the thinner wires are the backup-light circuit.

To troubleshoot: check for power going into and out of the switch, wiggle the shifter while you test, and jump the connector to confirm the backup bulbs work on their own.
