How To Install/Repair/Replace Wiring Harness?
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.
