HaHeHo Trailer Tow Rear Bumper Wiring Connector Harness for Ford Transit 2015-2019 — Direct-Fit Plug-and-Play, Sealed PVC Jacket

HaHeHo's CK4T-13B576-KE trailer tow rear bumper wiring connector harness is a direct-fit, plug-and-play replacement that restores towing lights and signals on 2015–2019 Ford Transit 150/250/350 vans.

If your Transit’s factory rear bumper towing connector is damaged, corroded, or missing, this complete harness kit provides the parts needed to re-establish a reliable trailer electrical connection. Engineered to match the OEM fit and wiring footprint, the kit ships with the connector, harness wire, mounting bracket and hardware so installation is straightforward and tidy. The cable is jacketed for resistance to abrasion and heat, and the sealed connector helps keep moisture and road grime out of the electrical contacts.

How will this harness work with my 2015–2019 Ford Transit?

The harness is built as a direct replacement for factory part numbers including CK4Z-13A576-B and 9U5Z-14489-MAA, so it aligns with the OEM connector layout and mounting points. It plugs into the vehicle’s existing wiring harness at the rear bumper and provides a standard trailer connector for lighting and signal functions.

• Fits Transit-150, 250, 350 and 350 HD models from 2015–2019.
• Direct replacement design — no cutting or splicing required on compatible vehicles.
• 3.7 ft wire length for convenient routing behind the bumper.
• Includes bracket, screws and cable ties for clean installation.

What does the kit include and how durable is it?

The package contains everything needed to mount and secure the connector at the rear bumper: one trailer towing connector, one harness wire assembly, one mounting bracket, two screws and five cable ties. The harness uses a PVC outer jacket and a sealed connector body to protect against abrasion, temperature extremes and road contaminants.

• Connector and harness wire pre-assembled for plug-and-play fitment.
• PVC jacketed cable resists wear, heat and debris exposure.
• Sealed connector housing minimizes moisture and dust ingress.
• Mounting hardware included for a factory-like finish.

Is installation difficult and what tools will I need?

Designed as a direct replacement, the harness typically installs without modifications. Basic hand tools are sufficient for most installs: a screwdriver or socket for the bracket screws and wire cutters or pliers to trim and secure cable ties. If you encounter factory clips or panels, simple trim-panel tools speed access to the bumper wiring area.

• Mostly plug-and-play — no electrical splicing on compatible Transits.
• Standard tools: screwdriver/socket and wire cutters or pliers recommended.
• Cable ties included make routing neat and secure.
• Installation time varies but is usually under an hour for experienced DIYers.
