1980 XS650SG harness revamp

[CafeSG]

I have a couple questions in hopes someone on here knows anything at all about J120 Mitsubishi igniter boxes. These are 5 pin modules with a C pin for coil, G for ground, B for battery, IGT for trigger and IGF for feedback for misfire. How do you wire up to the coil with one single input? Isn’t there supposed to be two? An orange wire and a red white to coil from igniter module is what I understood from the stock schematic.

That diagram is good for 6-7 pin igniter units. The igniter unit I have is 5 pins and I’m trying to find out how to wire in the ignition coil with only five pins

I think the 2nd wire to the coil is nothing more than switched power from the ignition switch (fed through the kill switch). It doesn't need to be connected to the igniter box.

An absolute life saver thanks!
