I am attempting to install a cruise control on my Ryker. I am tapping into the throttle wires. Below see a schematic of my wiring. This is a roster 250-1882. I am using magnets for vss. Everything seems to work fine until I plug the yellow wire from cruise control (ecu circuit 2,) to the bikes throttle sensor 2 + (yellow/red wire).
It throws the bike into limp home mode.
Any ideas what I am doing incorrectly?

Reason: a see atta tic... = schematic? ;-)
The yellow/red wire is power to hall sensor 2. You need to cut and splice into the signal wires green/black (sensor 1 signal) and green yellow (sensor 2 signal) I would think.
I have an update on my Rostra cruise control in my Ryker rally.Thanks dickp, For your input. you are absolutely correct. I now have the unit working properly. The instructions do not explain very well at all. As soon as I get the wires tied up and my bike back together I will repost with photos and instructions and placement of the control. This is the rostra 250-1882 for electronic drive by wire cruise for hot rods and part #250-3742 pickup coil and magnets on the drive shaft. I am so excited to test it once it is together. Stay tuned.
Thanks Rykerrally for the update. I agree, the instructions are not very comprehensive. I am very interested in installing one myself. Curious to me that Rostra uses magnetic pickup on the driveshaft and not a VSS signal. I would like to see how you did that.
I installed a traditional Rostra on my Suzuki Boulevard. I did not use the Rostra controls - a simple SPDT switch is all that's needed. I did not use an on/off switch; just tapped the brakes to disengage.
Dickb, Rostra does have units that wire to the vss, but what is nice about this unit is it can be adapted to any wiring setup and the drive shaft is do accessible on the Ruler. It is very accurate. Photos and my install instructions coming soon.
by the way dickb, how does the cruise you installed on your Suzuki work. Like like a nice clean install of the switch.
Quite well. It has several DIP switches to configure number of VSS pulses and throttle response that took some experimentation, as Rostra has no instructions for motorcycles. It does drop a few mph up hills and gains downhill. I suspect this could be improved by further experimentation with the switches. As there are no switches on yours, I'm guessing that the unit "learns" and adjusts itself?
There was an emergency flasher switch in that position, but as I never used it, it was the perfect location for the cruise switch - just move your thumb.

I probably won't be riding it for a couple weeks, I will be away from home, but when I get back I will try to do a video or photos of of installing using it. And using it..
Hi everyone, I have finished installing and test driving my Ryker Rally with the Rostra Electronic (drive by wire) cruise control. It is absolutely flawless. One push of the button increase or decrease it does it 1 mile an hour. Brake cancels it out just like in an automobile. I used the Rostra 250-1882, with the magnetic sensor and the control # 250-3472. This unit is used on specially built hot rods that have an open or visible drive shaft. No fooling with the vss wire on the bike. I bought my unit from The control store on line. they are awesome, and has a technician that really knows the unit, just don't say it is going on a bike, act like it is a hot rod. His name is Michael. So I have posted some photos of the install thanks to my man doing all the electrical. If you have any questions please don't hesitate to contact me. Good luck. So much better than the throttle lock.
Dickb, no I did not. I originally installed one, but it kept clicking like something kept setting it off even with ignition off. I removed it and test rode it. It works just fine without the relay. I have the sling mods tour bags on it. It works great.
SKiZo, yes that is all. It has a rotating sleeve so you can angle it any direction you need. I put some shrink wrap on it for water protection, not shown in photo.
I added a Rostra control on a 2001 Ford ZX2 Escort. For such a small straight shift engine, it worked perfectly. I just used a couple tiny momentary switches mounted to the steering wheel and connected through some relays with the included but not connected wiring in the steering column. Was pretty surprising how well the inexpensive (but not cheap) system worked.

Rykerrally, thanks for trailblazing this. I followed your lead, but did not use a supplied control. I used pushbutton switches on the switch pod for convenience and a factory look. The wires were snaked through the existing conduit, and a connector added to make assembly and any necessary disassembly easier.
Rickb, very clean set up. Did you use the ground and 12volts at the switch point? Is the cruise on all the time And the two buttons are start/ resume and coast? I really like that. So how does it work for you. Glad you did it. And glad I and my man could do it to show others.
Yes, I used the aux power connection for power and ground. I tapped into it and left the original connector in place. As this circuit is already protected by a 5A fuse, I did not use the fuse holder supplied by rostra.
The button on top of the switch cluster is push - on, push - off for cruise on/off. The bottom two are momentary Resume/Accel above Set/Decel. I'm learning to find the buttons by feel with gloved hands. The first switches that I got were flush and could not be located by touch very well. These have a high head and are easier to locate.
Under the left headlight cover are three black factory connectors: a 4-pin, 6-pin, and 12-pin (they may be in a different order, as I removed and replaced them from their mounts and I may not have replaced in the same order as original). The top connectors go to the handlebar controls, and the bottom halves to the wiring harness. The 6-pin connector is the throttle connection. The green with black stripe is the Throttle Sensor 1 and the green with yellow Throttle Sensor 2. Cut and connect these two at the wiring harness connector per the Rostra instructions. (if you get these wrong, the bike will enter Limp Home Mode as soon as you try engaging cruise.)
The gray connector is my added cruise control buttons - more on that next.
I ran 4 wires to the cruise control switches using the factory wire loom for the left switch pod. As stated, the On/Off switch is a push - on, push - off switch; the others momentary. Make the 4 wire connections to the cruise module per the Rostra wiring diagram. As explained, I added a connector so that the switch pod can be readily removed if necessary. As this added connector has no mounting point, I wrapped it in foam to keep it secure.
The brake connection can be made here, at this wire bundle that runs along the bottom of the frame to the rear of the bike. The Brake wire is white. There are two white wires; use either.
I solder then use Liquid Tape on these splice connections, then rewrap the bundle with black electrical tape. I ran this connection, along with the speed sensor wires, to the cruise module using wire loom (which I strongly recommend).
The Brake + connection on the cruise module can be simply wired to switched 12V power (aux power). It is a required connection for the module to function.
Speed pickup
Rostra supplies a mounting bracket for the speed pickup coil, but I used a piece if 1/8" sheet aluminum with a slot cut in it and a cable clamp.
I've put 3 of these on my Spyder. The 1st one was a vacuum unit. The next 2 were the electronic version. The vacuum unit was OK. But the electronic units were much improved. They lasted between 2 and 3 years each. Water got to every one of them. I am now looking at doing this a 4th time. they used to be about $100.00. They've gone up just a bit over the years.
