Cruiser/ Cruiser S – Main Connector Replacement GuideUpdated a month ago

The main connector is the bundle of wires that links your controller to the LCD, voltmeter, brake levers, PCB, horn, and light buttons. Proper care and installation are key to keeping your scooter running smoothly.

What the Main Connector Does

• Red brake lever wires: 2 pins

• Black LCD wires: 6 pins

• Blue horn/light buttons wires: 5 pins

When ordering a new main connector, it comes as a bare bundle of wires. The 11 pins will not be pre-grouped, so you’ll need to set them up yourself.

Purchase Links:

• Main Connector

• Cable Connection Pins (also available at local hardware stores)

Troubleshooting Tips

Even a new connector can run into problems if pins or wires are damaged:

• Bent or missing pins – can make the LCD, brake levers, or controller appear faulty.

• Thick wire pins – those connected to the brake levers or LCD can be damaged and affect functionality.

• Pinched or damaged wires – any crushes or cuts along the main connector can cause issues.

If you’ve replaced the LCD, controller, or brake levers and the problem persists, check the main connector and wires first. Often, fixing the pins or removing a pinch solves the problem without replacing expensive parts.

Tools Needed

• Allen key set (or multi-tool)

• Pliers

• Terminal removal kit

• Wire cutters

• Electrical tape

• Hot glue gun

Important: The battery must be unplugged during this repair. Sparks can occur if wires are live.
