I'm 50/50 on using that light. I know It hasn't been useful for the past 20 years. In turn, It could spare me maybe sometime from being stranded on the side of the road. idk, I'll get creative once i have it torn down for the install.

Looking at the CL diagram they have the load shed relay which I understand is what shuts everything off in order to supply all battery power to start the bike.



I don’t have an r11s specific diagram but I’m guessing they should be similar. I have seen other diagrams call this a relief relay. Wire color and numbers are the same.



The r11s manual calls it a relief relay. I assume I should tie the green blue wire in to the cruise control module.

I plan to add the fuse in to one of the empty spots next to the heated grips.

Only open question is the speedometer wire. Hopefully the CL module will work with the r11s design.

Everything else should wire up same as the CL diagram.

The wire from the speedometer is a pulse count that goes to the turn signal to cancel the turn signal. You should be able to tap that wire for the speed pulses.

For stuff like this wire I use positaps to connect to verify it works, then make a more permanent connections.

My S only has the four fuses in the holder on the left side, I have no fuse box on the right like for heated grips.

Have you put together a parts list of what you've bought already? How can we help you?

you could put in a dual color led into one of the existing instrument cluster indicators
so it would be green for one function and red for the other and both on for both

As expected fitting the RT bowden box is difficult but I am making progress.

Ordered this little LED bulb. Going to use it as the battery warning light hidden somewhere under the dash and modify the existing light to be amber for the cruise.

Getting closer to getting the RT bowden box to fit. I had to raise the ignition coil about .5" and cut the tabs off the box. Have yet to figure permanent mounting. My revised throttle deflector should arrive tonight so i should be able to set the cable lengths for the grip. I ordered another bowden box assy to use the longer cables and 90 deg fittings to attach to the throttle bodies. I will have to cut, drill, c'bore, and re-solder the cable ends. Getting the proper lengths will be difficult.

Throttle deflector: Throttle cable kit

Cable chart: BMW Motorcycle control cables

Thanks Anton Largiader for the very useful info.

For the cable lengths, is the other side connected and the adjustment set mid-stroke? or is it the cable completely removed from box and then pulled to one side for measurement? I assume the latter and if so my cable lengths would be different because the bowden boxes are not the same? Am I correct?

Here's what I'll do:
  1. Install the oem cables to the throttle grip
  2. Adjust to mid-stroke
  3. Measure RH & LH free length
  4. Install new mounted RT box
  5. Resize both grip cables to proper length (pull-pull)
  6. Set to mid-stroke
  7. Install new longer TB cables
  8. Cut and measure proper free lengths from original

Hopefully this will get me to where I want so I can move forward with the cruise control mounting and wiring.

Just curious...

Obviously you're well into it now but did you consider my suggestion of running the actuator cable directly to the throttle tube thereby not having to mess with the bowden box?

If so what steered you away? ... just wondering if there is a downside I'm not seeing.

I did consider it and I do agree that there is no down side to your set up. I just really don't mind taking the extra work to fit the RT box but I also wanted to use the throttle switch that is in the box. This gets me as close to OEM cruise as I can get. I understand its more work than whats necessary but I enjoy the challenge.

I thought the switch may have been a part of it, I considered it when doing my installation. With both brake functions, the clutch handle, the power switch and ultimately the ability to manually override the actuator I felt I could live without the throttle switch.

That switch failed on my LT about 50k miles ago and I never replaced it. It's clever setup though and very sensitive... be aware of its adjustment if/when troubleshooting.

The space is proving really tight as expected. Still have a little ways to go with mounting the box.



I do really like the pull pull set up though.



OEM Right side free length - 3.180"



OEM Left side free length - 3.365"



Anyone know why these free lengths are so different from each other? I'm really certain that everything is seated properly and cable set in the pulley groove. This could also be why I have had a long time issue with adjusting right TB. I had this same issue: Cable Problems

Seems like the bracket/pulley geometry on the 1200 TBs must be different from one another. Can't think of another reason... as long as nothing is out of alighnment inside the bowden box as you say.

It looks like there is a broken cable strand in that first pic.

This was with the OEM r11s bowden box with all cables installed only pulled off the tb to measure. I haven't made the new cables yet. Only measuring and taking notes before I modify the cables. My sequence of photos are out of order.

The more and more I think about it I may just ditch the rt bowden box and go the same route as you. I just don't like the way I need to mount the box. Its too large. oh well... Now I just need to design the slack tube. So glad I have a 3D printer.

So far this is my concept for the slack tube. I still have to get dimensions.

That looks awsome! A few points to consider...

- Check the BMW actuator to see if there is an interal feature to apply backpressure on the cable to maintain slight tension... not sure how BMW accomplishes it (mabe not necessary due to the design of the bowden box). The Rostra unit did not which necessitated adding the spring to apply that tension.

- If the spring is needed selection is important. The spring will effectively try to open the throttle so it needs to be only strong enough to maintain very slight tension and keep the cable from wadding up at the throttle tube when throttle is manually applied. Not so strong that it hinders the throttle from closing on its own.

- Something I didn't think of when fabricating the PVC tube I used was weatherproofing... need to keep water out. Ended up wrapping a plastic bag around it and securing with tie wraps. Would have used heat shrink if I had thought ahead....

Good point on the waterproofing! I believe it is sprung back in the bowden box. I'm not 100% sure of this yet. I will have to investigate it further. There is a slack / adjustment device as shown in the picture below. Could a spring be added there? maybe. Again I have yet to investigate further.



For now I put the bike back together so I could ride. Waiting to order new parts. I did order this switch. Fingers crossed for if the connectors are the same, if not i'll have to re-pin them.
