Don't run the revere rotation sensor wire to the hot of your solenoid. Yipes, that goes to stater side,-- You don't need that to get a spark.

Have you wired your kill switch in yet.

There are two crankshaft position sensors, one connected to the G and L wires, and the other to the Y and R wires. Both are needed to generate the timing signals necessary to generate spark, and neither should connect to ground. The B wire may be connected to either the terminal on the starter motor, or to the terminal on the starter relay that goes to the starter motor; that is electrically the same. If the engine somehow starts spinning backwards, it will drive the starter motor, which will act as a generator, but it's output will be negative; a negative Voltage at the ignitor will stop the spark. You can leave that pin on the ignitor disconnected, and will probably never need it, but there must be a reason Suzuki engineers thought it was needed.

It's in the factory service manual; some time ago I found an electronic copy, which really comes in handy for this kind of discussion.

Here is a color coded one for a 90. The only difference between the 87 and the 90 is at the ignitor box. You can compare the wires there, but for everything else the color one is much easier to use.

I can't seem to win the lottery. I think I have used up all of my good luck riding motorcycles.
