Wire harness oil cooling pump

The Electrical Wiring Diagram (more info) shows the oil pump is attached to connector A30 on the Engine Room Main Wire harness, for which the part numbers are listed in catalog Figure 82-02, Wiring & Clamp: 82111-47P20 (list price $4,282.29) for “G” (Premium or Advanced) grades, or 82111-47V00 ($4,001.49) for “E” (Plus) grades.

A complete wire harness wouldn’t usually be replaced, however, due to its high cost and the complexity of the installation: the harness has dozens of connectors, including some on the instrument panel side of the firewall. Indeed, wire harnesses are among the few parts for which the Repair Manual doesn’t provide removal and installation instructions.

Rather, a damaged or defective harness would usually be repaired using the techniques and repair parts described in the Electrical Wiring Diagram. For example, an empty housing of the type used for connector A30 is available (part number 90980-12A29), as are repair wires (pigtails with terminals) (part numbers 82998-24420, 82998-12790, or for gold-plated, 82998-12780) and splices.
