Installation is simple, the kit plugs in under the hood; No wire cutting or splicing; Kit comes with an illuminated rocker switch for control and to indicate when the front axle is being overridden; Designed to allow the operator to manually disable the front wheel drive mechanism by holding the hubs in the free (2WD) mode with the transfer case in 4WD low range; By allowing the front wheels to be disengaged, maximum torque is available to the rear wheels; This will also allow for sharp "All The Way Over" turns without the front axle u-joint hopping or binding; With this kit installed, the front wheels will NOT be driven through the transfer case; Allows to have full power and torque while in a high gear reduction applied to the rear axle(s) only
