Wired up the motor holders this evening so I could test them out.
I crimped on the connectors and put electrical tape on them.
Tucking the wires inside the legs to clean up the look a little I decided to do the same to Patches motor holders as well.
Drilling a hole in the frame to pass the wires through I wired them up and tried them out on a battery manually.
Here is a funny video of ED moving for the first time :)
