Dodge sells a harness that uses the oem external pump power and ground to trigger a relay in that harness to supply power back there. They tap into the truck harness connector that is hidden behind the driver side plastic wheel well, in between the plastic and cab fire wall. The harness instructions show which pin in the connector to tap into.
FWIW and IMHP I'd go to autozone and get an external pump made by airtex before fooling with an in tank. It'll push close to 20lbs with a good free flowing fuel filter.
