Typical wiring harness.

Wiring harnesses, also known as wiring looms or cable harnesses, are used throughout the vehicle to group two or more wires together within a sheath of either insulating tape or tubing Figure 36-57. Often, harnesses on modern vehicles contain many wires, each terminating at crimped terminals inserted into connector or harness plugs. There are usually a number of harnesses within the vehicle interconnecting with various connector plugs, as required to form the wiring system of the vehicle. Wiring harnesses run around the engine bay, through the dash and interior cabin, and to the rear of the vehicle. They are attached to the vehicle with harness fasteners such as body clips or wire ties, and rubber sealing grommets are used when the harness passes through the metal bodywork.
