Shift assist pro wiring - where is it?

[Doodle]

Back from a lengthy defection, recently taken delivery of a 13GS without Dynamic pack (for suspension related reasons). It was agreed when doing the deal that they would retrofit the shift assist at the first service, which is booked in a week or so. However, taking a peek at the back of the gearbox I'm struggling to see where the redundant connector is hiding, and starting to suspect it's ommitted from the loom for non-dynamic bikes.

Does anyone know where the connector would join the loom (or have a Dynamic bike up in the air/disassembled to snap a picture)? I'm bracing myself for a "discussion" when reality drops while on the ramp.

TIA

its just a switch that notices you kicking the gear lever then kills the spark to the plugs - on the way down it asks the computer to open the flyby wire throttle a smidge to try and make less of a mess of that change - so I guess two switches one up one down -

its one sensor and is listed under the box - unusual - they have changed from the link rod switch they had on earlier bikes - the engine loom lists one part, so I guess you need to look harder

In your usual inimitable style, thanks for contributing absolutely nothing I didn't already know - I'm fully aware of how it functions and where the sensor module lives. There are no additional blanked connectors, and nowhere visible on the nearby loom that one could be taped.

Hence back to my original question, if someone knows which part of the loom it branches off from, that'll narrow down if the wires exist taped up in the loom and need terminating, or if it's genuinely not there.

Not sure what you feel you need to do, the switch is built into the transmission and is likely wired to a connector at the back of the case just inboard of the shift shaft. Finding that circuit would require pouring over schematics and disassembling parts of the bike, to achieve nothing. Obviously the techs will know how the QS is enabled and what parts are necessary. What is your goal in finding this circuit?

There's an external module that sits externally in line with the shift axle to capture the motion - I suspect it's just a reed switch as the gearbox fiche shows a sodding great magnet that attaches to the middle of the axle. A google of engine images shows the machined inverse top hat on the back of the motor that it resides on.

In terms of the techs knowing how the QS is enabled, I'm not currently convinced. When I mentioned it while booking the first service (in person), the amount of squirreling was not reassuring. The reason I want to know is that it's the difference between an hours work, and an extensive refit that the dealership will almost certainly try to bail out of - if there's an impending bunfight then I'd like to be prepared.

The 1300 does not use a load sensor on the external link rod. The switch is inside the transmission. The shift link rod on mine has nothing. It is highly likely enabling QS is simply a software update.
If you were trying to get a service rep or manager to explain it, they will obviously have no clue how this is done. Trust the BMW tech to do this, they are the ONLY one who will know how to consult the documentation and get the job done. Why do people always think a trained BMW tech will have no clue? I guarantee they will know more than you or anybody on this forum. It's very likely they have not done this particular job yet because almost nobody buys a bike without it and then wants it. They do however know how to read the tech document and get a particular job done. They do this every day, all day.

And if you're worried about cost then ask for the quote. Don't go in looking for a fight. Let them do the job and pay the GD bill, that's how it's done.

I never said it did. Go back and re-read my exact words, and then compare them with the parts diagram and some images of the rear of the engine casing.

Also re-read the initial line of the first post - It was agreed when doing the deal that they would retrofit the shift assist at the first service. Asking for a quote and deciding if I was willing to pay the sum went out the window weeks ago. The deal was predicated on having the exact specification requested, that's already bought and paid for.

I'll be the first to agree that BMW techs should have the answer, but as yet that hasn't been demonstrated. Either the service manager conveyed their answer (and they don't know), or they didn't ask the techs and just fudged it themselves. Either way, it's not overflowing with positivity right now, and the concept that trained technicians are infallible and absolute in their knowledge is deliciously optimistic. If that were true, I wouldn't have the job I do.

I think we can call time at this point.
