Wacker Neuson 5000180744 Trailer Electric Brake Wiring Harness

The Wacker Neuson Trailer Electric Brake Wiring Harness is a genuine OEM component designed for the LTW6K, LTW8K, LTW20Z1, and LTW20Z3 series light towers, including Tier 4 interim and Tier 4 Final configurations. Sourced directly from Wacker Neuson, this harness is manufactured to the exact connector layout, wire gauge, and circuit specification of the original part. It covers an extensive range of LTW variants — cold weather builds, custom configurations, LED and MH lamp versions, and vertical mast models — so you can order with confidence that this is the correct harness for your machine. Verifying your model number against the fitment list before ordering is always recommended.

Key Features

• OEM-Matched Electrical Specification — Manufactured to the correct circuit layout, connector type, and wire gauge required for trailer electric brake operation on Wacker Neuson LTW light towers.
• Drop-In Connector Compatibility — Harness connectors and routing match the original installation points, allowing straightforward replacement without splicing or adapting terminals.
• Broad LTW Series Coverage — Fits LTW6K, LTW8K, LTW20Z1, and LTW20Z3 light towers across Tier 4, Tier 4 interim, cold weather, custom, LED, MH, and vertical mast variants.
• Restores Trailer Brake Control — A damaged or failed wiring harness breaks the signal between the tow vehicle and the trailer electric brakes; replacing it restores full, responsive braking control during transport.
• Brake System Safety Compliance — Trailer electric brake circuits are a transport safety system. Using a genuine OEM harness ensures the brake signal is delivered at the correct voltage and without resistance-induced delay, keeping the braking system operating as intended under towing conditions.

The trailer electric brake wiring harness carries the electrical signal from the tow vehicle's brake controller to the electric brake actuators mounted on the light tower trailer axle. When the driver applies the brakes, the harness transmits the activation signal that engages the trailer brakes in coordination with the tow vehicle, reducing stopping distance and trailer sway. If the harness is damaged, corroded, or has a broken circuit, the trailer brakes may respond intermittently or not at all — creating a serious towing hazard and potentially putting the machine and operators at risk.
