Changing Plugs and Breaking Wires - HELP
As for reinstalling the connector, you would have to open it up with some pliers or something then re crimp it together. Don't be ripping the wires off the plugs, you have to pull on the thick sleeve part closest to the heads, not the wire, that's how they get screwed up. If it were me and I messed up 4 I would probably wrap up my job for the night and get some new wires and start fresh tomorrow.
