Described herein is a rear zone module and rear zone controller that minimizes wire gauge and current draw. The rear zone module shares outputs amongst several functions including rear windshield wiper, heated back window, power liftgate controller and the like. These outputs can be shared because not all functions are required to be active at the same time. For example, a vehicle includes a rear zone module (RZM) that includes at least a power liftgate (PLG) module, heated back window module, and a rear window wiper module. The vehicle also includes a controller configured to selectively control current with respect to at least the PLG module, heated back window module, and a rear window wiper module. The interconnections between the RZM and controller are minimized by sharing the interconnections as the PLG module operates mutually exclusively from the heated back window and rear window wiper module.
