The G4X CivicLink (95) and CivicLink (98) Plug-In ECUs have been designed to be used with the factory distributed ignition system or an after market multi-coil ignition system. Four ECU ignition outputs have been connected to the main header. Ignition 1 is on the pin used for distributed ignition whereas other channels are wired to unused header pins. Terminals for the factory connector can be purchased from your nearest Link dealer. It is the installers responsibility to make sure any after market ignition system is wired properly and correctly configured in the ECU.
