Yes, the Curt 56314 custom wiring harness is compatible with both Kia Optima and Kia Optima Hybrid models.
The Curt 56314 has two circuit ratings: Signal Circuits are rated at 3.0 amps per side, and Tail/Running Circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
You will need: Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool. A 3/32" drill bit is also needed if you must drill a pilot hole for the ground wire screw.
Yes, you must disconnect the negative battery terminal before beginning installation. This is a required safety step performed in Step 1 of the installation process.
After removing the trunk floor coverings and rear scuff panel, pull back the felt liner to locate the vehicle's taillight wiring harness connectors. Separate the connectors from the taillight housing carefully, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors on the driver side, ensuring the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the harness end with the green wire.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. The area must be free of rust, dirt and paint. If no suitable existing screw is available, drill a 3/32" pilot hole and use the provided screw. Secure the white ground wire using the ring terminal and provided screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The converter box should be positioned in a location that is accessible but out of the way.
Route the black power wire from the vehicle battery as shown on the included CME-PCL-INS sheet. This separate instruction sheet provides the specific routing path for your vehicle. The battery connection must be fuse-protected with a maximum 10-amp fuse.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route the 4-flat to the center of the vehicle. Secure any loose wires with the provided cable ties to prevent tangling and damage.
Reinstall all items removed during installation, including trunk floor coverings, felt liner, and rear scuff panel. Reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test the wiring harness for proper function using a test light or by connecting a properly wired trailer.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
