Step 1:Labelling the wires connections using the masking tapes. This step will help you make the installation very quickly, significantly if the wires’ colors are faded away. Step 2:Disconnect and remove the car battery from the vehicle using a socket wrench. Step 3:Disconnect the primary connection of the engine body wire harness. Step 4:Take a jack, jack up the vehicle, and disconnected all the wires from under the car. Step 5:Install the new engine wiring harness. While installing new wiring, ensure that the wires route away from the hot exhaust pipes and other engine parts. Once you are done, reconnect the battery to the vehicle, and you are good to go. If your truck is experiencing injection fault codes, idling or running rough your factory wiring may have a short or loose connection. Our wire harness connectors are made of good copper wire, good electrical conductivity. All wiring harnesses are equipped with good sleeves (slidable for the required installation) to improve the performance and efficiency of the engine. The wiring harness has undergone quality inspection before leaving the factory.
