Decreased installation time: Many vehicles require miles of wires to run. The wiring harness assembly process greatly simplifies the manufacturing of these vehicles by integrating all wires and cables into a single device. In this way, installation becomes a simple matter of "putting in" the wiring harness instead of running all the wires individually.
Security and safety: When wires and cables are bound in a single harness, the individual components are safer from the adverse effects of vibration, abrasion and humidity. The space has been optimized and the risk of electrical shorts is reduced because the wires are constructed into a bundle that is not easily bent. When the wires are tied in the flame-retardant casing, the risk of electrical fire is also reduced.
