Oceanialend Waterproof Main Wiring Harness for KT Controllers — 1.53m Black, 24–72V Sealed

Oceanialend 1T5 913AG is a waterproof main wiring harness designed to link KT controllers with display, throttle and brakes for reliable e-bike operation.

This durable 1T5 cable harness is built to keep the critical electrical connections on your electric bicycle secure and dry. It supports systems from 24V up to 72V and was designed with KT controllers in mind, so common e-bike components — display, brake, throttle and controller — plug together quickly and stay connected while riding. The harness measures about 1.53 meters, has a black jacket for a clean look, and uses color-coded connectors to minimize installation mistakes.

How does this cable keep connections safe in wet conditions?

The 1T5 913AG harness uses water-resistant construction and sealed connector bodies to reduce the risk of moisture intrusion that can corrode contacts or cause intermittent faults. Its outer jacket and mating plugs are engineered to block water and resist environmental wear so connections remain stable after exposure to rain or spray.

• IP-style waterproofing in the connector housings to limit water entry
• Corrosion-resistant contact materials for longer electrical life
• Durable outer sheath protecting internal wires from abrasion and damp

Will this cable work with my e-bike setup and KT controller?

The harness is optimized for KT controllers and supports a wide voltage span from 24V through 72V, making it compatible with most common e-bike systems that use KT electronics. Color-coded, multi-pin plugs match standard KT pinouts for straightforward integration with displays, throttles and brake sensors.

• Designed specifically for KT controller pin configurations
• Compatible across typical e-bike voltages (24V–72V)
• Includes distinct colored plugs to simplify connection mapping

What are the connectors and how do they simplify installation?

The harness includes a red two-pin brake connector, an orange three-pin throttle connector and a green five-pin display connector, each keyed to prevent incorrect mating. These clearly differentiated plugs reduce installation time and help ensure reliable wiring without guessing which lead belongs where.

• Red 2-pin brake plug for secure brake sensor hookup
• Orange 3-pin throttle plug for standard throttles
• Green 5-pin display plug for common KT displays and controls

How long is the cable and what routing options does it offer?

The harness is approximately 1.53 meters (about 5 feet) long, providing ample length to route between a frame-mounted controller, display on the handlebars and other peripherals. The black jacket helps the cable blend with most frames, while the flex pattern allows tidy bends for neat installation and secure clamping.

• Approx. 1.53 m total length for flexible routing choices
• Black outer sheath for a discreet, professional appearance
• Flexible construction supports clean cable runs and tie-downs

Who is this product for? The Oceanialend 1T5 913AG waterproof main cable is ideal for e-bike builders, mechanics and riders upgrading or repairing KT-controller-based systems who need a reliable, weather-resistant harness. It suits anyone replacing a worn OEM loom, retrofitting accessories to a KT controller, or assembling a bike where clean, color-coded connections and a long, flexible cable are priorities. If you use KT controllers and require dependable plug-and-play wiring that resists moisture and wear, this harness is designed to streamline installation and reduce connection problems on rides.
