V8 Power Distribution

V8 Power Distribution

Feed from the positive battery terminal (C0192) is supplied to fusible link 2 and fusible link 5 of the passenger compartment fuse box (C0632) on an R wire. Fusible link 2 (C0591) provides a constant battery feed to the Engine Control Module (ECM) relay (C1895) on an R wire.

Fusible link 5 of the passenger compartment fuse box (C0588) is connected to fuse 15 of the rear passenger compartment fuse box (C2024) by an R wire. Fuse 15 provides a constant battery feed to the fuel pump relay, which is also located in the rear fuse box.

ECM Relay

Fusible link 2 of the passenger compartment fuse box (C0591) provides a constant battery feed to the ECM relay coil (C1895) on an R wire. The earth path for the relay coil (C1895) is controlled by the ECM (C0604) on an N wire. The energised ECM relay (C1895) provides a feed to fuse 51 of the passenger compartment fuse box (C0584) on an RW wire. Fuse 51 (C0585) supplies a feed to the fuel pump relay coil (C2022) on an RW wire.

Fuel Pump Relay

The fuel pump relay coil (C2022) receives a feed from fuse 51 of the passenger compartment fuse box (C0585) on an RW wire. The earth path for the relay coil (C2022) is controlled by the ECM (C0331) on a BP wire. The energised fuel pump relay provides a battery feed from fuse 15 of the rear fuse box to the fuel pump (C0114) on a WU wire. The fuel pump is earthed on an N wire.
