Looks like a broken wire leading to rear injector

Phil (Marcum of Marcum Racing) wont get to it til late monday or early tues...but after describing the symptoms he says it sounds like the wire is broken/stretched at the rear injector...apparantly Harley was saving on a millimeter of wire for a couple of years on Road Kings... said he has seen more than a couple do it...fingers crossed cuz thats like an hours labor and some solder.

Default Wire Failure

2007 FLHX - Check engine light came on and began to run roughly. Checked engine codes to reveal PO263 (rear injector low). Limped it home and traced problem directly where wire enters connector at injector, conductor had parted within wire insulation. Ordered 2 new connectors with pigtails and installed, reassembled and all is well. Engine vibration at the connector had caused the failure.
