Section 494 (OEM Electrical Wiring Diagram Introduction): Introduction: Splices
WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Splices directly connecting to the power distribution are best represented on the power distribution schematic in "Power Distribution." Splices connected to grounds can be seen completely in "Grounds." For all other splices, a reference is given to each where that particular splice can be best viewed.
