The Lenco Trim Tab Actuator Extension Harness at 20 ft gives you extra reach between your trim tabs and the dash on bigger hulls. The 20 ft length lets you route the loom around tanks and bulkheads instead of straight across gear in the bilge. The connectors match standard Lenco trim tab actuators so the cable clicks into place without cutting or crimping. This Lenco harness runs a continuous 20 ft marine grade cable so you avoid extra joins that can corrode out at sea. The wiring spec is set for recreational trim tab loads and sits under a 5 year recreational use warranty from Lenco. The length makes sense for hard top rigs where the dash can sit 15 to 18 ft from the transom. For most trailer boats that is enough slack to follow existing factory looms.

Q: Can I shorten the 20 ft harness if I have excess cable?

It is not intended to be cut or shortened. The connectors are moulded to suit Lenco gear and cutting the cable removes those ends. Extra length is usually managed by coiling the spare cable in a dry, ventilated locker. Any modification may affect performance and may void warranty support.

Q: Is this harness suitable for commercial or charter vessels?

The harness carries a 5 year warranty for recreational use only. Commercial or charter applications typically see higher duty cycles and different compliance requirements. Many operators still use this type of harness, but warranty support and service intervals may differ. Check with your surveyor or electrician before fitting to surveyed vessels.

Q: Can this extension harness be used with both port and starboard actuators?

The harness is a generic Lenco actuator extension and is not side specific. The same 20 ft cable can be fitted to either port or starboard trim tab actuator wiring as required. Installers normally match the colour codes at both ends. Best practice is to label the harness during fitment to avoid confusion later.

Q: Do I need special tools to connect this harness?

No additional crimp tools are normally required because the connectors are pre-fitted. The harness uses plug style ends that mate with compatible Lenco trim tab actuators and control wiring. Standard hand tools for routing and securing cable, like cable ties and cutters, are usually sufficient. Always follow general marine wiring practices for strain relief and chafe protection.
