backup light switch.

i did safety inspections for SC back when this state had them. The law reads, Any light installed has to work. That includes a high mount brake lamp you added yourself. Only way around this law is remove the reverse lamps.
The plastic pin sticking out of the shift tube has been replaced with a bolt in other threads here. I think the column will have to come out to do it. The rare earth magnetic things were glued onto the shift collar in a thread here also. I think that was a much later model but same concept and solution. He did reverse lamp circuit and neutral safety circuit with them.
