How can I wire up the LEGO 2838?

Question

I would like to know how to hook up the LEGO 2838 9v motor. I understand that the Power Functions extension wire is compatible with the 9v system, but how on earth do I wire them up?

Answer 1

To wire 2838 motor, you have to use one PF extension cable, one end connected to PF power source (either battery box or IR receiver), the other end has a 9V compatible plug on bottom. Unfortunately, 2838 also has its connector on bottom, so you also need a 9V cable (such as this one) to connect them.
