can be rewired to suit my prop controller boards.
Originally there are 4 wires:
2 from the DC supply and 2 to the load.
Black goes to the – solder pad.
Red goes to either + solder pad.
Yellow goes to the – OUT solder pad
to fit into the slots in the plastic casing.
The 3 pin connector is wired to suit the sensor
input on my prop controllers.
