I just have the first one with a 15 amp fuse. I can’t find the diagram for this anywhere

READ ANSWERThe top for my 2001 996 Carrera cabriolet will not activate up or down in high temperature conditions. If I love it inside and allow it to cool down, everything works fine. My research indicates that the convertible top relay is highly sensitive to heat and internal solder joints age, expand and crack under heat. I'm fairly sure this is the problem, as it is a 25 year-old car. What is the correct replacement relay and where is it located? Under dash or behind rear seats
