Hi,
After a lot of reading, this is my first post. Excited to be part of the forum! 🙌
Since I bought my 911 SC (from 1979) last year, I've been trying to figure out how to deal with these components, that won't turn on, and seems to be on the same wiring:
- interior cabin lights
- cigarette lighter
- radio
- frunk light
- clock (is not running)
- odometer (not running)
I have a wiring diagram of SC's from 78/79 and I've checked fuseholder 18, which unfortunately only have one wire mounted, meaning one is missing (see photo).
I've read a lot, but I don't have a lot of experience with electrics. I don't get how to get started. How do I find the missing wire(s) to connect? Do I have to split all dash etc apart or can I open something in th frunk to get more access?
Any help highly appreciated

🙌
