hello. i have a 2005 6.0 Lariat Powerstroke & i can move my wiring harness while the truck is running & it misfires & runs rough. i can be driving down the road & go to get on the truck a little & the wrench light & the check engine light come on & it starts to run rough & misfire but then i go to turn it off & it it back on & it’s perfectly fine, all codes & lights are gone. does anyone know the part number for the ficm wiring harness? i already have the engine wiring harness. thank you for your time
