I have replaced wiring harness part number 918503K111. It may be too early to tell but my car is performing flawlessly so far. This wiring harness came directly from South Korea. The cost is about half of what the dealer wanted. This harness is an exact fit for the car, however, the part number is slightly different from the original. The harness is a little bit shorter leading to the alternator. There is no detrimental effect to the installation. In order to change the harness you will need some mechanical skill. The installation is easy except for the lead that attaches to the starter. The starter wire is part of the harness.
To change the harness, first drive the car up on a pair of ramps, so that the starter lead may be accessed from below the car. Next remove the battery, (disconnect the negative lead first) so the wires that lead to the engine junction box may be routed. Remove the two wires at the junction box, remove wire from the alternator. The wire to the battery is already removed.
The tricky part is removing the starter lead. In order to remove this wire the shield on the starter must be removed. There are three attach points securing the shield. Two bolts, 10 mm socket size, secure the shield to the front of the starter. These bolts are accessed from underneath the hood. One of the bolts also holds a wire harness routing bracket. Next you must get beneath the car and locate the third securing point, which is a stud with nut. Once the shield is free it must be moved out of the way. I was unable to remove the shield so I just positioned it out of the way. Now one can remove the nut that secures the wire to the starter. There is a small gauge wire that leads to the starter solenoid that has a push-on type connector at both ends, disconnect this wire. Next, disconnect all of the harness routing clips (look at the new harness to see how to release clips). There is one bolt securing the harness next to the battery, remove this. Install new harness, enjoy!
