Here is another headache for you.
I have a frequency block that connects and disconnects the starter motor to start the engine based on engine RPM. It used to work fine on VS commodore as a part of the remote engine start because I knew where the tachometer wire was. But when I tried to install it to Lancer 2007, I was at loss to find the tachometer wire. One American website listed black green or black yellow colours from the ignition coils to use as tacho outputs but these did not work. Lancer uses coil on plug ignition on each cylinder, and these have ignition modules built into them, so they only receive low signal from ECU. This signal is probably not high enough in power or frequency to be fed to my frequency block. Using injector wires did not help either. My last hope is the dash tachometer display but it is very hard to work out which wire controls it.
PS. Lancer 2007 does not have a starter motor relay like many other cars. Instead, the ignition switch connects the battery +12V wire directly to the starter motor solenoid wire to switch on the starter motor. Also, each coil on plug has three wires (white for +12V, black for Ground and another colour wire for switching the coil on and off from ECU)
