Does anyone know how the Mazda igniters should be connected?

I have Tracy’s EC-4 and the wiring shows how some of the wires are connected but colors don’t necessarily agree,

Leading igniter 2 conductor connector red and white.

Single conductor connector black wire

Trailing igniter  4 conductor connector red, white, yellow and grey wires.  2 conductor 2 brown wires.

I am concerned about leaving wires unconnected.

Thanks for any help
