First will start by saying i've read the How To on this!
Apologies about starting yet ANOTHER thread re: Traction Control! I'm sitting on my drive with wires everywhere trying to install the T/c Switch in my 2004 coupe.
Finally managed to wrestle the ABS plug off and near on every pin as a wire in it. Pin 31 is easy to identify as er the 'How To' but as my car has ESP i need to use Pin 25 but dont know how to determine which wire?
