Prodigy Brake controller
Should be plug & play.....check under dash behind center cup holder/ash tray for where to plug in harness. Then check in main fuse compartment for fuse/relay being installed----owners manual will give info 'fuse--tow section'.
As for the in bed 7 pin receptacle.
Just get an extension kit.
Unplug factory harness at rear bumper receptacle, plug in extension harness---pull factory harness back in, then run extension receptacle to location in truck bed and install
Easy-peasy...........
