Use the male to male replacement cord to connect the Pro 69 controllers to other devices. Note the AC Infinity control outlets each include one of these cords already. AC-EXR9
Use the male to female extension cord if you need to locate a control outlet more than 10' away from the Pro 69 controllers. This cord includes a female to female UIS adapter. Just connect this to the device's male to male connector to extend the reach of the 69 Pro controller. Up to 5 of these extension cords can be added together. Replaces AC-EXQ9
