The Phillips Industries Liftgate Dual Pole Installation/Conversion Kit is available with everything required for a liftgate dual pole installation or a single to dual pole conversion. The dual pole cable has a dedicated positive and ground line directly from the tractor batteries to improve reliability between kingpins and 5th wheels. The extra reliability in the connection ensures that the charge to the liftgate batteries is continuous, and not intermittently relying on the 5th-wheel/king-pin ground combination. When using the dual pole cable, users are providing a cleaner signal to the liftgate batteries and other auxiliary devices.
