Since you asked nicely Smile I have the exact same igniter and coil, as shown
in the picture, sitting on my dining room table. It has a 4-pin green plug
attached, and wires like so (reading from left to right...

Red wire: either IGt or IGf and goes to green plug (from there to ECU)
White wire: either IGt or IGf and goes to green plug (from there to ECU)
Brown wire: Power supply, goes to coil +ve and then to green plug
Yellow wire: Tacho output, goes to green plug
Black wire: goes to coil -ve

The IGt wire takes the trigger signal from the ECU to the igniter. The IGf
signal is sent from the igniter to the ECU to let the ECU know that the
igniter has fired. You need both connected for the engine to run.

There should only be one wire on the coil negative, but there may be
several on the coil positive, as that wire is often tapped to get a key
switched supply for other purposes.

Smoke from the wires means you have a short, or have found some
other wire of passing a heavy current thru a thin wire Smile

If the engine struggles when the coil HT lead is connected to the dissy,
it suggests that your timing is over advanced. Try retarding the distributor
by turning it clockwise as far as it will go.
