PDC Circuit Operation
A feed from the battery positive terminal is connected by a R wire to the engine compartment fusebox, where it passes through fusible link 1 and fusible links 8. Fusible link 1 is connected in series with fusible link 7. Fusible link 7 provides a battery feed to the auxiliary circuits relay contacts.
Fusible link 8 is connected to the passenger compartment fusebox by an NW wire. From the passenger compartment fusebox, current flows to the ignition switch on an N wire.
