The Servo is the little blue motor on the pen holder. The servo cables wires must be in this order: Orange, Brown, Red. Always check the position of new servo cables before running Makelangelo. If the servo is connected without being swapped the Makelangelo will not power on. Marginally Clever swaps new servos when they test each one.

While gently pulling on the red wire, slide a pin under the hook of the black JST header to carefully lift and release the crimp pin. When you get it right the crimp pin will slide out effortlessly. Lifting too hard can break the hook so be gentle!

Note which side is up on the pin - there is a tong that catches on the hook.

Once both crimp pins are released, reinsert them with the new order. Be sure to keep the tong on the up side to catch on the hook.

Remember: when connecting the servo to the extension cable, the red wire of the servo goes to the black wire of the extension cable.
