A Relay Start Wiring Harness Wiring Harness is also sometimes called a Cable Harness. It’s a group of multiple wires that are bundled together and joined to the connector at both ends. Complex wiring harnesses can have wires that split off from the group like branches of a tree. Typical uses for wiring harnesses are where electric service reliability is of utmost importance, such as off-road heavy vehicles. Specifically, off-road heavy vehicles contain masses of wires. However, by binding these wires and cables into a cable wire harness, they can be better secured and not face the adverse effects of abrasion, temperatures, moisture, dust, and other factors.Attributes:• Flexible enough to bend and twist• Providing a more organized work environment• Works well in tight spaces where a large number of wires on separate connectors won't fit.Applications:A Relay Start Wiring Harness Wiring Harness is used to connect the Relay Switch and Engine to the Power.
