B.1 The IG5 Outputs
The IG5 has five outputs, four of which are dual purpose. Refer to the wiring diagram
Appendix E for pin numbering of the IGNITION OUTPUT plug. Pin C is always an ignition
output and provides the only ignition output when there is a single ignition coil connected to a
distributor. Pins A,D,E &F are either ignition outputs or auxiliary outputs. They can provide
one or more ignition outputs as required for direct fire ignition systems. They can also
provide auxiliary outputs if not required for an ignition function in which case they will be
designated as Aux Out 1, Aux Out 2, Aux Out 3 and Aux Out 4 as marked on the loom
diagram. For information on igniters refer to appendix B4 IGNITERS.
The IG5 always allocates its output signals in the same order. It will use up to 4 ignition
outputs and those outputs not used for ignition signalling are available for Aux functions. The
sequence of utilisation is as follows.

* Although strictly there is no distributor on a 1 cylinder engine, selecting Direct Fire will
cause the IG5 to wait for a Home signal.
