Hi, does anyone know what these stepper motor wire colors mean?
(left to right)
Black - Orange - Red - Yellow
I want to connect them to a pololu A4988
There is no standard for stepper wire color codes.
I found a stepper motor with this color combination as secondary wires...

Keling KL23H51-24-08B
The first Darwin RepRap with an Arduino controller (Generation 2 Electronics) used this stepper motor. It has 200 steps to one revolution (1.8o per step). It actually has 4 coils (which means it can be wired as both a bipolar and unipolar), but we join up the wires to turn it into a bipolar motor. It is much cheaper than the Nanotec, and with half-stepping it is almost as accurate. (The Keling KL23H51-24-08B is also used in the Eiffel prototype).
Bipolar - Serial
This configuration is suited for our driver boards. It has higher impedance and higher resistance which means it draws less current. In this mode it can handle 1.5 amps, which is ideally matched to our L298 based boards. We recommend wiring it in this configuration. Not certain it is your motor, but here it is:
| Name | Color |
|---|---|
| A | Blue |
| B | Green |
| C | Brown |
| D | White |
You will also need to splice the following wires together:
- Red and Yellow
- Black and Orange
