Ignition Switch Circuit Supply

In the engine compartment fusebox, a feed from fusible link 8 is connected to the passenger compartment fusebox by an NW wire. The feed passes through the fusebox and is connected to the ignition switch by an N wire.

When the ignition is switched on to position II, a feed from the ignition switch is connected to the passenger compartment fusebox by a Y wire and passes through fuse 25.
