Bill- an ideal candidate. This looks like you have can motors in the trucks. The blue and yellow wires are the motor leads. Just trace the wires back to the board to confirm.
The swap is easy. Power out to one motor (yellow), power back from same motor (blue) gets connected to the same color wire from the other motor. The other yellow remains in tact. That's all it takes.
Not sure if the motors turn in opposite directions but you need to check before closing it up. If so just swap the wires between the motors.
Love the new set.
