Hello, I just recently bought an 85 mr2 5 speed. I am new to the chassis and don't know much about the car itself. The brake lights and hazards work but the reverse lights don't turn on. I assumed the bulbs were bad but I found out they weren't even in. After replacing them with the proper bulbs, They still don't turn on. What fuses/relays/switches do I have to check to begin diagnosis?
