Hardware Connection of the Pan Tilt Zoom Raspberry Pi Camera
Arducam sell the Pan Tilt Zoon kit in components to cater to the different customization needs of the custmers, so you may need to assemble the kit before you can start using it. As long as you follow the diagram below, you can keep the system up and running even after swapping certain parts.
In this illustrator, the different colors of the jumper wires are just to make it easier to distinguish them from each other.

Therefore, instead of its color, you should rely on the position of the wire to correctly connect the jumpers.
