I want to install a speed display unit in a 2002 UK Ford Focus 1.6. Installation instructions for the unit (Defi VSD BASIS) suggest tapping into the Speed Pulse (SP) wire going to the ECU but I don't want to do that as the ECU connections are hidden behind a tamper-proof shield that I don't want to er... tamper with!
Can anyone suggest another way to tap into the Speed Pulse signal inside the car (I don't want to run wires through to the engine compartment). Perhaps the Speed Pulse signal is fed to the radio?
Thanks for any insight you can give.
