The CURT 56438 is designed for trucks with T5 wiring location, which is behind the passenger side rear bumper. To confirm fitment, check your vehicle owner's manual or contact the vehicle manufacturer. The manual does not list specific vehicle makes, models or years, so you should verify compatibility with CURT or your installer before purchase.
The CURT 56438 is a custom wiring harness with a converter box that connects your truck's taillight wiring to a 4-flat trailer connector. It allows you to tow a trailer with proper lighting control. The system includes signal circuits rated at 3.0 amps per side and tail/running circuits rated at 6.0 amps total.
You will need: ratchet, cutting tool, 10mm socket, flathead screwdriver, and socket extension. These are the minimum tools required for installation.
The package includes a custom wiring harness with fuse holder, a black converter box, a 4-flat dust cover, double-sided tape for mounting the converter box, and cable ties for securing wires. The manual does not specify whether the 4-flat connector itself is included or must be purchased separately.
Yes. You must disconnect the negative battery terminal before beginning installation. Keep the negative cable fastened down and away from the battery during the installation process. Reconnect it only after all other steps are complete and the fuse is installed.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating. The fuse holder is included with the harness, but the fuse itself is not installed until after the harness installation is complete.
Mount the black converter box in a flat, protected location inside the vehicle near the taillight using the provided double-sided tape. The manual emphasizes that failure to mount the box in a protected area can cause loss of warranty, product failure, overheating and potential fire. Choose a location that is sheltered from moisture, heat sources and physical damage.
1. Locate the gray plastic connector between the battery and driver-side fender and remove the protective cover. 2. Insert the custom wiring harness (with fuse holder) onto the vehicle harness, ensuring connectors are fully inserted with locking tabs in place. 3. Attach the ring terminal end to the positive battery terminal. Do not install the fuse until the harness installation is complete.
1. Locate the vehicle taillight wiring harness connectors behind the rear bumper along the passenger side frame rail. 2. Remove the protective cover, taking care not to damage the locking tabs. 3. Insert the custom wiring harness connector into the vehicle connector, ensuring it is fully inserted with locking tabs in place.
Route the 4-flat connector to the center of the vehicle close to the receiver hitch and secure it with the provided cable ties. This routing protects the connector and keeps it accessible for trailer hookup.
Secure any loose wires using the provided cable ties. This prevents wires from moving, chafing, or becoming damaged during vehicle operation.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. The manual does not specify the product's maximum rating in amps or weight. Check your vehicle owner's manual or contact CURT for the specific product rating and your vehicle's lamp load capacity.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
After installation is complete, test for proper function by using a test light or connecting a properly wired trailer. This confirms that all connections are secure and the wiring harness is functioning correctly before towing.
Yes. Install the provided 4-flat dust cover after installation is complete. This helps prevent corrosion of the connector when it is not in use.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. The manual does not specify an exact interval, but regular checks before towing are recommended to maintain warranty coverage and safe operation.
