Replacement LH rear driver-side door jumper harness compatible with 2009–2014 Ford F-150 Crew Cab that replaces OE 9L3Z-14631-CAA for reliable door electrical connections.

If your Crew Cab’s rear left door wiring is frayed, intermittent, or failed entirely, installing the B.ZSSY Rear Left Door Jumper Wire Assembly restores the electrical link between the door and vehicle body. This direct-fit jumper harness is designed to replace Ford OE part numbers 9L3Z-14631-CAA and 9L3Z14631CAA for model years 2009 through 2014 — excluding trucks equipped with rear heated seats plug. The assembly comes as a single LH rear driver-side harness built from ABS plastic and complete pre-terminated wiring to simplify swap-out and get your door electronics working again.
