A male to male servo lead joins two connectors that both need a plug. This one is 100mm long and has the same small plug a servo has on both ends, with metal sockets inside. Each end pushes into the open receptacle end of a servo extension or Y lead, or straight onto three header pins on a receiver or servo driver board.
You can use it to join two extension leads end to end, to add an extension to a Y lead, or to link a receiver to a flight controller when both have header pins. The plugs have no polarity tab, so they fit JR, Futaba and Hitec style receptacles, but they also fit either way round. Line up the colours at each join: black goes to black or brown, red to red, and white to white, orange or yellow.

Wiring & getting started
Wiring diagramServo lead
- Switch the power off
Unplug the battery or USB before you join or remove any servo lead.
- Find the signal pin on each side
On a lead, the lightest wire is signal (white, orange or yellow), red is positive and the darkest is negative (black or brown). On a board, look for S, + and - or SIG, V+ and GND printed beside the pins.
- Plug in the first end
Put the white wire on signal and the black wire on negative, then push until the plug sits fully home.
- Plug in the other end the same way
The wires run straight through, so the white wire must be on signal at both ends. Black on signal at one end means that plug is upside down.
- Check only one side feeds power
The red wire joins the positive pins on both sides. If both sides have their own power, such as a receiver battery on one side and an ESC or flight controller BEC on the other, take the red wire out of one plug. Lift its little plastic latch with a pin, slide the wire out and tape over the bare contact.
- Check it works
Power up and move the stick or run your test code. The servo should move as it did without the lead. If it does nothing, one plug is reversed or not pushed fully home.
