If you are referring to the rear flexible printed circuit board, there are no new ones existing! I know cause I have spent days trying to source one at any cost. You basically have two options: 1) roll the dice on a used unit or, 2) find someone to try and repair yours. This same problem has derailed my car for over 6 weeks now and I'm on the 3rd used one to see if it works. The problem with these is the delamination on the copper ribbon circuits and the overall age of the units. There is also a custom gauge replacement option but it's costly and not really a plug n play deal. Good luck!
