Re: 06 Mustang seatbelt replacement
I believe the seat belts in the newer Mustangs are be connected to the RCM (restraint control module) which controls the airbags. However disconnecting that wire shouldn't cause the airbags to deploy or anything crazy like that. With that said I'm not certain if disconnecting that wire will cause the RCM to throw a trouble code causing the airbag light to turn on (which will be a pain the rear to turn off) so I would strongly suggest that you make sure the ignition is turned off when disconnecting it. You might also want to go the extra step of disconnecting the negative battery cable as well.
