Can a car wiring harness be a problem?
Many vehicles will go through their entire service life without any issues related to the wiring harness or its connections. But it is not unusual when diagnosing a problem with a vehicle system to eventually locate the root cause at a damaged wire, terminal, or connector.
Where do you plug in a wire harness?
Our custom wiring harnesses use two or more OEM connectors to plug in at the taillight assembly and provide a standard trailer socket to allow a trailer to be plugged into your vehicle’s power system. This harness provides a 4-way flat connector socket and comes with a circuit-protected converter.
What to know when troubleshooting a wiring installation?
When it comes to troubleshooting a wiring installation, testing is everything. A lighting problem can originate at any point along the wiring on either the tow vehicle or the trailer, so it is important to determine not only what is causing the problem, but where it is located.
How can I find out if my wire is bad?
Find the wire being tested by its color. Look for damage to the wire. Turn on the ohm meter and place the dial on the ohms reading. Clip the two test leads together and record the reading which should be infinite ohms.
How to find a bad wire in a car wiring harness?
Cut the outer cover on the wiring harness open at the suspected bad spot. Find the wire being tested by its color. Look for damage to the wire. Turn on the ohm meter and place the dial on the ohms reading.
What causes a wiring harness to stop working?
If there isn’t any electricity flowing to the accessory, the problem may caused by a faulty wiring harness or a bad switch. To test the wiring harness, first remove the wires connected to the accessory. Carefully trace the wires back to the first connection point you encounter.

What should the resistance of a wiring harness be?
In good circuits, where the wire is functioning properly, resistance should be .3 ohms or less, or .5 at the most. Repeat this procedure for the other wires in the wiring harness until the bad section is identified.
