The wire from relay pin 30 goes to the 16 amp fuse side of the 2 fuse
holder and from there to the fridge 12 volt element circuit. This fuse
should only get power when the engine is running. The 8 amp fuse needs
power all the time for the kitchen. Use a volt meter to be sure this is
the case when you are done.
