Same wires to same motor - opposite terminals
item#2 is just a plain dc motor no sensors
I believe only LionChief + has speed/cruise control.
100% swap the wires on the main board and not the engine side. You can usually slip a blade under the connectors tabs and slip the wire with metal prong off of the plug, do that to all of the wires and re-arrange them opposite of where you removed them. I would do this one motor at a time as to not confuse the leads. To be clear, one yellow and one white wire out of the plug for motor A and re-install yellow where white was and vice versa. Do that for the other two conductors and you are done. Just not sure if you will be stressing the engines since they aren't being "lashed up" or MU'ed like some AA sets are.
I hope this helps!
