Recently purchased 996 with aftermarket Nav unit installed (Pioneer AVIC Z2). Original installer has bypassed the "parking brake" limiter. Fine, but it displays a warning screen on every startup that requires me to touch to clear. I don't care about the bypass, but the warning screen really bugs me. I would like to reverse the bypass. I searched. While there is tons of info on performing the bypass, there seems to be nothing on wiring to the parking brake correctly. Can someone help me find the parking brake "hot" wire so that I can wire this thing to spec.

Thanks
