On a 2005 FX4, the largest, upper connector (with the locking handle) has an intermittent connection to the dome light / supervision circuit. Sometimes the dome light works, and then it doesn't. This is bad because the aftermarket alarm depends on that circuit. I can press on, or jiggle the harness connector and toggle the fault.
