Hi..

I am in need of some help from some of you technical gurus.
I have now installed my Zeitronix Zt-2, and it seems to work well, NICE piece of kit. I have installed the TPS function, and this work to.. so far so good. Now I want to install the RPM signal but I am VERY unsure about wich wire is the correct one to take this signal from. I have tryed the wire from CPS pin 6 on the ECU plug but it didnt work. Before I go any further.. could it be pin 4 or??

I would really like it to be under the dash near by the ECU, because it is easy and neat (it where I have installed the Zeitronix)

The Zeitronix manual says, and I quote "RPM input. 0-12V square wave signal, tach signal OR primary (low voltage) side of the ignition coil"

My car: ´93 Escort Cosworth, without coilpack if it should matter

HELP PLEASE
