Happy to report brick started on a first try with the new wiring. Thank you everyone for your help. I have one more question,  very small one in a grand skim of things, but I have an issue with the kill switch lol.
I am using a switch from cbr1000rr and no matter how I wire it, the kill switch works in reverse.   My guess is I have to reverse polarity inside the switch. Diagram attached.

Glad to hear it worked for you.

I am currently working on the same model of k1100 as yours, with the same ecu  can you share your final wiring diagram here pleāse?

Hey bud, the first few comments of this post/topic contain several k1100/4v wiring diagrams.
Engine wiring for this specific ecu are mentioned in these diagrams.

Happy wiring

Hi Kaos, thanks for the quick reply

I do have the oem wiring diagram for both 93- and 94+ k1100, my k1100 is a 93 model equiped with ignition output stage and co potentiometer.

 However, I encountered problem when installing the m-unit blue and would like to see if Lucas could share his finial wiring diagram for me to cross check my work.

In gist, my k1100 runs after m-unit installation but it would suddenly black out when test drive (for like 5 mins run).  Hall sensor and the heat shrink of the ignition unit checked correct and therefore i suspect there might be sth wrong with my wiring.

Did you blow the fuse? If so, what's amps on the fuse?
Otherwise its overdraw from a single outlet and your m-unit will shut down. It has this protesctivs measure built in.
This is the (my own) wiring diagram i am running on the same v2.1 ecu.

Works on all v2.1

Oh I guess I might have overdraw the output,

But meanwhile can you share your diagram in a higher resolution version, please

Do keep in mind a single output is 12v and 10A max.
