That's twelve splices in front of the back seat and twelve more in the dash... damn... that's a lot of splicing. At least I used bullet connectors so once I undo what I did I can re-do it after I get the twenty four new bullets in place...

For the MID I simply added 6" of wire to each connection. I turned on the system before I moved the MID and it still lit up, didn't change anything besides adding wire to the MID, Tested continuity and everything matched up so I don't think I could have mixed up a wire.
