Yes. You must disconnect the negative battery terminal before beginning installation. This is a required safety step to prevent electrical hazards during the wiring work.
The manual does not specify whether professional installation is required. The installation involves panel removal, wiring, drilling, and electrical connections. If you are not comfortable with these tasks, consult a professional installer.
Yes. You must drill a 3/32" pilot hole in the vehicle frame to secure the white ground wire using the provided screw. The drilling location should be a flat spot near the taillight, free of rust, dirt, and paint. You may also use an existing screw with nut in the vehicle frame if one is available nearby.

The harness has three main wires: yellow wire (driver side taillight connection), green wire (passenger side taillight connection), and white wire (ground connection). The black converter box connects to the vehicle battery via a black power wire. Route the 4-flat connector to the center of the vehicle when in use, and store it out of the way when not in use.
The white ground wire connects to the vehicle frame using the provided ring terminal and screw. Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole. The area must be free of rust, dirt, and paint.
The black converter box should be mounted on a flat spot inside the vehicle near the taillight using the provided double-sided tape. This location keeps the converter box secure and out of the way during normal vehicle operation.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the vehicle. When in use, route it to the center of the vehicle. Secure any loose wires with the provided cable ties to prevent tangling and damage.
1. Disconnect the negative battery terminal. 2. Remove trunk floor coverings and rear scuff panel. 3. Remove side felt liner push fasteners on the driver side. 4. Locate and separate the vehicle taillight connectors. 5. Insert the harness end with yellow wire between the connectors. 6. Secure the white ground wire to the vehicle frame. 7. Route the harness end with green wire to the passenger side and repeat steps 3–5. 8. Mount the black converter box with double-sided tape. 9. Route the black power wire from the battery (see included CME-PCL-INS sheet). 10. Route and secure the 4-flat connector. 11. Reinstall all removed items and reconnect the battery. 12. Install the 4-flat dust cover.
Locate the vehicle taillight wiring harness connectors behind the taillight housing inside the trunk. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
You must remove: all trunk floor coverings, the rear scuff panel (by pulling out on the bottom and then up), and the side felt liner push fasteners on both the driver and passenger sides. Take care not to damage the alignment tabs on the back of the scuff panel or the locking tabs on the connectors.
After installation, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly. The manual does not provide detailed testing procedures beyond these methods.
After installation: 1. Reconnect the negative battery terminal. 2. Install the provided 4-flat dust cover to help prevent corrosion. 3.
