I searched the forums but came up zilch. I have an original MM control panel harness and new Happ 3" trackballs, with the red optic boards. The up/down works, but the left/right is the opposite of what should happen. If I son the ball left, the ball goes right. I'm sure this has come up before, so if anyone can point me in the right direction I would be grateful.
