Maybe as last resort. I could see it going wrong, in a big way.

Fancy 2 pole connector? No idea what that looks like, even after searching.

If wiring was an event in the Special Olympics, I'd probably come in last. <a href="http://www.customfighters.com/forums/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" >:-)</a>

Buy a nice 2 pin connector. Eg A molex or Deutsch. Run a wire from the battery to this plug. Run a wire to the positive terminal on your m-unit and put that in on the other position. The other side of the plug loop the fusable link between the two. Effectively you plug the fuse in as it’s one side of a plug and socket.

Just an idea, it’s Small, light weight has very few parts can be placed anywhere...

Like this but not like this. Replace the plug on the end with whatever fancy looking thing you’d like.

Thinking this morning about tinning wire ends for the main fuse setup. Common sense says when I tighten screws on the wire ends, the solder would break up. Read about wire ferrules, never seen one before. The M-Unit also uses screws to secure the wires, so I'll need ferrules and a ferrule crimping tool.

Just found this info. Doesn't really explain the problem. My bike does have a CDI ignition. Do I need a relay? Not clear to me why.

"If you think about how the m-Unit outputs work it becomes clear why a CDI will not work here, the Ignition Out provides 12v+ power which the CDI does not require. But by using a common 5 pole, normally closed relay we can make this work just like any other ignition. When the m-Unit provides power to the Ignition Output the relay opens the switched circuit. When the Kill Switch is activated the m-Unit cuts power to the relay in turn closing the switched circuit, grounding the CDI and eliminating ignition spark."

the relay provides the ground circuit needed to kill the ignition when you turn the engine off.

I understand that.

Why can't I just run one of the kill switch wires to ground, like the OEM wiring?

oh, sorry. my understanding of CDI is basic at best but I think that the relay is used to ground the capacitor in the CDI. if it isnt switched to ground to drain the capacitor off the ignition will continue to operate until the capacitor charge is used up, which I dont think will happen as the stator is still providing power to the CDI while the engine is spinning. the relay doesnt provide any power, just a ground to discharge the capacitor and kill ignition.

Normally, terminal 30 would provide power to 87 when the relay is activated but in this set-up it grounds the capacitor out. I would imagine a regular kill switch would work but I dont know how an M-Unit integrates into the ignition system. Kinda looks like this setup just makes ignition off controllable through the M-Unit switches.

If Im wrong, please correct me (anybody). Im certainly no expert here, just trying to figure it out like you...

It appears as if the M-Unit wants to control the kill switch in place of standard kill switch on the handlebars. Maybe this is for the M-unit to have a smaller rated switch send the signal to the unit and then kill the power.

If you are still using the handlebar kill switch, I would assume that you can ignore this whole installation step.

I believe the m-unit also has an alarm/security function, could be needed for that part of the functionality, or it could be so that you can use their handlebar switches.

Trying to figure out how to wire up the left handlebar switches using the m-unit.

Not as easy as I hoped. The headlight wires come out of the switch housing. Looks like I'll need to cut them and run them to the m-unit and back.

Using the switchgear (#47) from a WR250X.
Will report progress in a minute.

Yes it has
