BMW K100RS 92’ cafe racer “flying whale@
« on: April 13, 2019, 09:00:05 AM »
Hello everyone!!!!

This is my first attempt to make a cafe racer and bought a bmw K100RS 92’  for building  but I need assistance with the wiring I want to replace the stock handlebar switches so I bought the m-unit blue to change also the wire harness and the bep to replace the tachometer but my problem is I can’t find a wiring diagram for this model cause it has the matronic control unit and I am stuck. I found plenty diagrams for older models but nothing for one with matronic...
Can you give me some advice how to connect the matronic system to the m-unit?

Another problem is that you haven't navigated around the site enough. Electrical diagrams can be found in the Motorbrick Technical Directory. That is where I found this one.

This is a video showing m-unit replacement on a K1100 which also uses a Motronic management system similar to your moto's. You'll likely be getting more advice about this procedure here but searching the site should uncover additional information.

Maybe I was not clear on my original post I meant that I can’t find a wiring diagram for the m-unit connected to my specific model i already have this wiring diagram but unfortunately my electric skills are the worst than everything but from the video you send me the only I manage to understand is that what ever needs power I can pass the relay and connect it to the m-unit directly if I am correct...

greetings...

when did equipment providers stop providing the tech for their equipments proper operation...

and when did buyers of said equipment stop doing their own doo dillergence before buying the equipment...

Well usual when you provide an equipment that is vastly supported from many different manufacturers and models you provide just a general diagram and leave the rest to the consumer...

No cause my problem for now at least is not the bep but the m-unit wiring. Do you think they will be able to assist me ?!

I am looking a wiring diagram for the m-unit how to be connected with my specific K100RS Ed or someone who can give me some guidance on how to connect it due to tha all the wiring diagrams are for older K’s and not have a motronic control unit.

The wiring diagram in the link of Post#5 of the this thread is of a 4V K100RS with a Motronic. What type of instructions came with the m-unit?

There are many members who have worked with the m-unit with varying degrees of success. Click this link then scroll down for links to threads discussing the challenges. You could send a personal message to those members whose work interests you. The thread titled The Khan . . . is working on a moto with a Motronic but whether the electronic fuel injection control is Motronic or Jetronic, the installation seems similar.
