I need to get the car safety check that required to have this backup light. It is a 1978 Ford Lincoln Versaille (similar to ford Granada. I bought this to restore the car last year. Questions:
1/ I would like to know where the backup light switch is and how do you engage or disengage it.
2/ Once the switch is engaged, how does the backup light get its power? Basically, is the power to the backup light come from the switch or the switch act like a ground wire to complete the circuit where there is a live wire at the backup light and all it needs is ground.
Thx
