Hi,
The only thing I was able to go to a newer year. It should be the same or similar.
If you look below, it shows what I thought. Fusible links from the battery send power to the switch and fuse box.
I highlighted the fusible link that I need you to check. See if you are able to locate it on the 1992.
Let me know.
Joe
See pics below. I attached the entire power distribution system for a 1994, so it is close in year. I had to cut each pic in half to make them readable for you but overlapped them so you can follow from one to the next.
