26.4 Ignition coils wiring
After setting everything up, the ignition outputs of the ECU are ready to be connected to your coils or ignition
modules. FT ECU ignition outputs cannot be connected directly to dumb coils, only to smart coils (coils with integrated
ignition module) or ignition modules.
For 2 rotor engines, the gray wires are connected as the table below shows:
