Higo 1T4 Cable (Bafang) – 1-to-4 Splitter for E-Bike Wiring, IP65, 2 A

The Higo 1T4 cable is a passive 1-to-4 splitter built for Bafang e-bike wiring harnesses. It fits Bafang systems and other Higo 1T4 setups whenever the pin layout (pinout) matches. From a single main bus, it breaks out four separate connections for peripheral devices.

Those four outputs handle the display or speedometer, the brake sensors, the throttle, the pedal assist sensor (PAS) and the lights. Maximum current is 2 A, so the splitter suits signal circuits and small loads. Lights connect only when their draw stays under 2 A.

All connections use Plug & Play Higo connectors, so no soldering is required during installation. The plug and sockets press straight in without twisting. As a result, splitting out a harness at the handlebar or frame takes just a few minutes. The insulation is flexible and durable, which makes the cable easy to route under the frame or along the handlebar.

Key Benefits

• 1-to-4 splitter – one main bus is divided into four separate outputs for peripherals.
• Plug & Play Higo connectors – connect without soldering and without extra adapters.
• IP65 protection rating – resists dust and water spray while you ride in the rain.
• Maximum current of 2 A – suited to signal circuits and small electrical loads.
• Bafang compatibility – works with the standard Bafang / Higo 1T4 pin layout.
• Flexible, durable insulation – the cable can be routed under the frame or on the handlebar.
• Black colour – the cable blends in with the rest of a standard e-bike harness.
• Passive design – there is no electronics inside, so the signal is only split, never altered.

Who Is This Cable For?

This splitter is made for Bafang drive systems. That covers Bafang mid-drive units and Bafang hub motors whose harnesses use Higo type connectors. In addition, it fits other Higo 1T4 ecosystem solutions when the pinout matches.

Four peripheral devices connect to the outputs: the display or speedometer, the brake sensors, the throttle, the pedal assist sensor (PAS) and the lights. Lights are connected only when their current stays within the 2 A limit. The cable also works for extending a harness in the handlebar and frame area.

The product is useful when you are building or reworking an e-bike harness. Above all, it suits riders moving a controller into a new frame or tidying the wiring around the handlebar. Workshops choose it too, because it gives a neat breakout without any soldering work.

Technical Specifications

Installation

• Switch off the power and disconnect the battery.
• Connect the main Higo plug (the “1” side) to the controller or harness.
• Connect your peripherals to the four outputs.
• Do not twist the connectors. Press them in straight instead.
• Check that the cables do not pull tight when the handlebar turns or the fork works.

Why Choose the Higo 1T4 Cable?

Instead of four separate branches leaving the controller, a single bus does the job. Therefore fewer wires sit in the handlebar area, and the connections no longer tangle with each other. That difference shows most on builds where space around the stem is tight.

Higo connectors are an industrial standard in the e-bike world, and Bafang uses them in its own harnesses. Because of that, this splitter drops in without adapters whenever the pin layout matches. No soldering is needed at any point of the installation.

The IP65 rating means the cable can stay exposed under the frame. However, the connectors should still be kept away from high-pressure washing. The flexible insulation handles the movement that comes with steering and fork travel.

Frequently Asked Questions

Does the Higo 1T4 cable fit a Bafang system?

• Yes, provided the standard Bafang / Higo 1T4 pin layout is used.
• Higo connectors are Plug & Play, so no soldering is required.
• Identical looking connectors can carry different pin layouts. The pinout decides fitment, not the shape of the plug.

Which devices can I connect to the four outputs?

• The display or speedometer.
• The brake sensors.
• The throttle.
• The pedal assist sensor (PAS).
• The lights, as long as they stay within 2 A.

Can I run lights through this splitter?

• Yes, when the light current does not exceed 2 A.
• The 2 A maximum is intended for signal circuits and small loads.

Will it work with a Bafang mid-drive and a Bafang hub motor?

• Yes, both drive types are covered when their harness uses Higo connectors.
• Other Higo 1T4 ecosystem parts also work when the pinout matches.

Is this splitter waterproof?

• The protection rating is IP65, so dust and water spray are not a problem.
• High-pressure washing should be kept away from the connectors.

Does the splitter change the signal in any way?

• No. The design is passive and holds no electronics inside.
• The signal is only split between the four outputs.

Can I use it to extend my wiring?

• Yes, it also serves as a harness extension in the handlebar and frame area.
• The flexible insulation allows routing under the frame or along the handlebar.

For anyone assembling or reworking an e-bike harness, the Higo 1T4 splitter turns one main bus into four tidy Plug & Play outputs. With an IP65 rating, a 2 A signal capacity and a black jacket that matches standard e-bike wiring, it keeps the display, brakes, throttle, PAS and lights connected without a soldering iron.
