Rear Tow Harness HL3Z-13A576-D for 2015-2020 F-150 Without Parking Sensors

Rear bumper wiring for trucks without parking sensors

This replacement rear bumper tow harness is listed for selected 2015-2020 Ford F-150 trucks without rear parking assist sensors, using reference HL3Z-13A576-D. It runs between the truck's matching rear wiring and trailer socket. The package contains one assembled harness and five cable ties.

The harness has black corrugated loom, fitted mounting clips, a large rectangular connector with a red locking tab, a round connector with a blue insert, and two smaller branch connectors. Ground terminal hardware is fitted to the harness. The round connector is the harness-side connection for a separate trailer socket; a bumper-mounted socket with weather covers is not included.

Confirm the towing and parking aid configuration

Match HL3Z-13A576-D against the harness reference required for your VIN and installed bumper equipment. This is the version for trucks without rear parking assist sensors. Trucks with sensor wiring need a harness that supports those additional connections.

Ford lists the reference harness for specified medium-duty, heavy-duty or max-duty trailer tow equipment. These are vehicle option descriptions, not towing capacity ratings for this replacement. Confirm the truck's original tow package and compare every connector, branch location and mounting point with the harness being removed. A truck in the listed year range may still require a different wiring assembly.

Route and test the replacement harness

Follow the exact truck's wiring service instructions. Check the mating connectors and ground attachment for damage, secure the loom along the original route and keep it clear of exhaust heat and moving parts. Check that each connector lock engages, then test the connected lighting and trailer circuits required by the truck's equipment before towing.

Wire gauge, circuit pin assignments, current ratings and a waterproof rating are not specified. Use the vehicle wiring diagram for electrical diagnosis and connection identification. This harness supplies a replacement wiring assembly; additional towing functions depend on the truck's existing equipment and configuration.
