Tail Light Wiring Harness: How to Replace It
Imagine what a risk it would be when you are driving at night and then your vehicle's tail lights suddenly died. You would not want that to happen, right? That is why your tail light wiring harness is important. It allows the efficient transfer of electricity so that the tail light will maintain its illumination. Once your tail light wiring harness goes bad, you must replace it immediately. Here are tools and steps that you can follow:
Difficulty level: Moderate
Things you'll need:
- Wire stripper
- New tail light wiring harness
Step 1: Turn off the engine and let it cool down for several minutes before starting the replacement process.
Step 2: Loosen and disconnect the negative ground cable from the battery terminal. This can prevent any electrical difficulty or accident.
Step 3: With the help of the wire stripper, remove all the wires of the tail light. Put down just about one-fourth inch of bare wire. Take away the old tail light wiring harness afterwards.
Step 4: Before installing your new tail light wiring harness on the vehicle, you must fix the wires that need to be attached on it first. Trim a little portion of an electrical wire, which must be able to extend from the actual wiring harness up to the tail light.
Step 5: Put the initial joined connector on top of the trailer tail light wiring harness. Keep in mind that the wire should have a green color if the wiring harness contains seven wires. On the other hand, the wire must have a brown color if the wiring harness has a maximum of six wires.
Step 6: The next thing to do is to put in the other end of the separate electrical wire into the joined connecter, which you have placed over the trailer harness earlier.
Step 7: Grasp and crease the joined connecter afterwards in order to attach the wire of the tail light onto the electrical wire.
Step 8: Match the wires already placed on the new tail light wiring harness with those in the vehicle's tail light wires.
Step 9: Look for the end of the bare harness wires, and insert it into the end of the joined connector. Make sure that it will still match the color of your vehicle's tail light wiring. Secure the connection by means of the wire stripper once again.
Step 10: You may now attach your new wiring harness to the tail light. To do this, press your new wiring harness with gentle pressure towards the tail light connector. Make sure that it will be securely placed on its mounting area.
Step 11: Insert the next splice or joined connector on the area above the tail light. Afterwards, put the open end of the electrical wire securely into the splice connector. Tuck the connector in order to join the tail light lead and the electrical wire together.
Step 12: You may now reconnect the negative ground cable to the battery terminal. Test the efficiency of your new tail light wiring harness by means of starting your vehicle's lights.
