The back up lights are switched on the stering column. There is a two piece linkage that is attached to the shifter linkage on the transmission and then that goes up to the sterring column by the firewall in the engine compartment. It connects by the brake vacuum boost unit. Many times this linkage is removed by people when they install headers. To check and see if everything is eworking, start the car and slowly turn the part of the steering column by the dash by hand, it should be a piece about six inches in length. If the linkage is conneccted it will rotate as the shifter in the floor is turned. The backup lights are a part of the neutral safety switch on the sterring column under the dash.
