About Electric Wires & Connectors

Long before Power Functions and Powered Up, LEGO linked battery boxes, motors, lights and transformers with loose wires that had a plug on each end. These wires are listed as 12V / 4.5V because both systems used the same plug. 9V uses a different connector. The length in the name is given in studs, so measure your old cable the same way.

• Wires with a plug on each end, in different lengths
• Loose plugs in rounded and squared shapes
• Small connector pins and screws that sit inside the plugs

Finding the right part

• Compare the plug shape: rounded or squared, narrow or wide
• Search on the part number, or filter on colour and condition
• Looking for motors or lights? See Electric Parts or Electric Train
