# Acorn > Design and order custom XT30 and XT30(2+2) wire harnesses online with instant pricing. Choose wire length (30–3000 mm), 14/16/18 AWG power, straight, right-angle or tinned-lead ends, and wire colors. Assembled and 100% tested in the USA, ships in 1 week. Acorn is the harness shop of Almond Robotics (Almond AI, Inc.), maker of the Axol dual-arm robot. Acorn builds custom XT30 and XT30(2+2) jumper cables (the same connector on both ends) and pigtails (a plug on one end, tinned leads on the other) with instant online pricing. XT30(2+2) carries power plus two signal wires (usually CAN bus) and mates with the XT30(2+2) male headers on Damiao, MyActuator and similar robot actuators. Plain XT30 is the standard 2-pin power plug for batteries, ESCs and power boards.
