I just purchased the RPM sensor for my traqmate complete system installed on a 1985 Porsche 911 (3.2 motor with stock ignition. coil, tach) Does anyone know where/how to connect the traqmate RPM sensor wire? Directly to the back of the tachometer and connected to which lead? or to the positive or negative side of the coil? Does the SU need to be set to E or C?
I searched this forum, Pelican Parts, and Google, but could not find a clear answer for an 1985 911, so any shared experience would be appreciated.
