Signal circuits are rated at 7.5 amps per side, and tail/running circuits are rated at 7.5 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.

Yes, you must disconnect the negative battery terminal before beginning installation. This is the first step in the installation process and is required for safety.
Insert the yellow wire end into the top frame hole on the driver side. Fish it down the channel leading to the rear of the taillight connector. Route the end through the opening and insert it between the separated taillight connectors, ensuring the connectors are fully inserted with locking tabs in place. Reinstall the taillight.
Run a long fish wire into the top frame hole on the passenger side above the cargo door towards the center of the vehicle, using the hole from the removed dome light to guide it to the driver side. Fasten the green wire end to this routed fish wire and pull it back to the passenger side. Repeat the taillight connector installation process on the passenger side with the green wire end.
Mount the black converter box on the driver side inside the cargo area, on a flat spot on the upper corner inside the rear cargo door frame. Use the provided double-sided tape to adhere it.
Drilling may be required. Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt, and paint. Always check for hidden items behind or under surfaces before drilling to avoid damage and personal injury.
Route the 4-flat wire through the top frame hole where the converter is installed and down out the bottom of the 12V DC accessory hole. Coil the 4-flat wire for storage when not in use. Reinstall the 12V DC accessory cover after routing.
Reinstall all items removed during installation, reconnect the negative battery terminal, and install the provided 4-flat dust cover to help prevent corrosion.
Test for proper function by using a test light or by connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
Locate and remove the Phillips screws holding the taillight in place. Remove the taillight to access the vehicle taillight wiring harness. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end between the separated connectors, ensuring they are fully inserted with locking tabs in place before reinstalling the taillight.
Yes, you must remove the dome light located inside the rear cargo area above the cargo doors. This removal provides access for routing the fish wire that guides the green wire end to the passenger side.
