GENERAL INFORMATION The Purkeys Direct™ system improves the charging of liftgate batteries by utilizing a DC/DC Converter to boost the voltage for optimal charging. The boost in voltage overcomes the normal voltage drop caused by the extended distance between the liftgate batteries and the vehicle charging system.

Note: Ensure that the jacketed 4-conductor main harness enters the liftgate battery box through a dome nut or rubber grommet to prevent chaffing the harness, which could result in possible electrical short in the system. P: 479.419.4800 | F: 479.419.4801 | www.purkeys.net...
