The optional electronic interface module (PN 42R800) plugs into the factory Jeep wiring harness. It allows the use of the Rubicon lockers and sway bar disconnect with the RubiCrawler engaged, regardless of what range the factory T-case is in. For mud and sand you can run the 2.72 low-range of the RubiCrawler with the lockers on, or run the rear locker only while in two-wheel drive for high-speed sand running.
