RPM Signal

I'm looking to get my Glanza Tacho to work.
I have a standalone ECU with DIS ignition and a special Tacho wire directly form the ECU to connect a Tacho.

I have had this ecu tacho signal connected to my Tacho meter but it wasn't even moving the needle. i measured it at idle and was reading 13.4V

now comes the question;
what kind of signal is the stock tacho signal?

i'm reading about block signals up to 12V and others up to 18V.

i have disassembled my stock Paseo Tacho and noticed the negative side form the ignitor is connected to it.

who can help me out?
