Control Box, Power Wedge, 5-Pole, w/ H-Bridge, MMDC/MUX, 12. For all older Malibu models with this computer control system. To match, check your current module and make sure it says "mmdc"  or "mux"; if not you will need a different box.

If you have the older style 3-pole wedge system you will usually have to convert to this control box to get the updated 5-pole actuators to work. Will require this control box and 5615008 (qty 2) as well.
