can anyone help me out in need of wiring diagram for left-hand combination switch-
managed to strip switch down and work out what connection are on the switch itself but need to where they go from there ie dash/ECU module.
got aftermarket race switches and can't seem to get any functions working ( set,trip or abs button) doesn't make sense so need the comfirm harness is good as its had some harness repairs at the cluster plugs


the bike is imported from states to uk with UK ecu if that makes any difference?.

I threw this together fairly quickly, so I hope everything that you need is covered in it:

Fantastic!! apart from abs switch missing that’s what I needed will check it out later
Also got no fuel gauge so reckon could be feed from pin7 (x9001) guessing standard 5volt feed I’ll be looking for ??

Like I said, I threw it together based on the information that was provided at the time.

PM me your VIN and I'll see what else I can dig up.

I'm surprised @sro hasn't chimed in yet

That’s a massive help so far, bought a non runner gen2 was imported from states I’ve fitted rck enabled uk ecu and at some point from an accident had cluster plugs and wiring changed and don’t match up colours needed some guide that’s a start cheers
Bike runs fine now just problems I’ve mentioned above

The fuel sensor should get it's power from effectively pin 7 of X9001 and the return side of the fuel sensor is on pin 8 of X9001. Measure the voltage at pin 8 of X9001 and see if changes with fuel level in the tank. Open circuit (fuel sensor unplugged) probably gives you an empty indication?

As for the ABS/DTC button on the left multi-function switch. This comes in on effectively pin 7 (same as the TRIP button) and goes out on pin 8 of the left grip connector (8-pin) which then comes in on pin 1 of X9001 on the instrument cluster control unit connector.

Have noticed the beemer diagrams are like rocking horse sh1t :frown2: .
also noticed they keep the same colour wiring but different pin location which was problem i had, having a closer look had 2010 plugs with small length of 2010 loom onto the 2012 loom colours matched up but different pin locations

all now working as it should like id said had some repair in the past using gen1 2010 connectors previous owner just joined the wiring to same color coding (can't blame him something I would have done) but using your diagram ignored the colors just done from pin numbers now all good

new to bmw club can't believe how much BMW make it so hard to find any diagrams and also mix it up between years.

Thanks again AussieAlien

The wiring diagrams are stored in ISTA. Which most people don't have access too. The general repair program called AIR which used to be RSD have never had them. They are too complex to really print out on paper. You would have multiple bits of paper to cover every control unit and the canbus system using wires for multiple jobs. I have access to all of it and even have a break down of pin outs for all control units for every model. I just lack the time and energy some times to chase up wiring diagram info among the many other things I am doing.
