Caming a goat

I found out today that the 0-6-0 goat does have pickups on the engine wheels but only the left side. So attaching a cam is easy and the picture below shows the cam being glued in place.
However Manuta does have the wrong color wire running to the frame. They are using the red wire which is for the right hand pickups. They should be using the black for the left hand pickup. I will correct this before installing the decoder.
