Hi there,
I'm currently installing my Zeitronix ZT-2 System. Sensors are already installed and working

Now I'd like to wire the Zeitronix to the ECU to get the RPM and TPS signal, but I don't want to cut wires of the car. So what's the best way to get the signal?

I tried to get the cables out of the connector which go to ECU Pin #4 and #10 (I think so...) but failed with this.

Any idea out there?
Thanks, Thom
