Hellbender,
When your new Rostra arrives, download BDF's (Brian Felice's) instructional tutorial.
It shows everything you need to know (with pics) about the install.
The wiring may look intimidating at first, but his tutorial explains it all well.
Look at it like this; first, it's the mechanical side... Installing the servo unit, the switch, setting up the dip switches, mounting and hooking up the servo cable to the throttle bracket.
Second, wiring it up.
Third, testing, and passing the initial diagnostic tests.
Fourth, test ride, once diagnostic tests pass.
I have installed Rostras now on 5 different bikes.
The C14 is by far the easiest to install. The hardest- BMW RT's.
Do yourself a favor... When ordering the control pad switch, get the one that has BOTH power ON light and the ENGAGED light. Also, you'll need to also order an additional relay, same as the one for the brake. Don't forget to order a mounting pad bracket for the switch.
The first time you do this, plan for it to take most of a weekend.
It usually takes me between 8-10 hours on a connie.
I installed my servo on the LH side, as BDF shows. I also installed my switch on the LH handlebar.
Did this for 2 reasons... 1) all the electrical you need to tie into is on the LH side, 2) I use my LH to use the switch. Also, the throttle linkage is on the LH side.
Others have mounted the servo on the RH, and it will work. YMMV.
Relax, read through Brian's tutorial, lay it all out, and study up first. Then follow it step by step.
You can do this.
If you have questions, we're here for ya, bro.
Once you get this installed and working, it'll be the best farkle you'll ever install on your bike.
About paying someone... If after reading BDF's tutorial you don't think you can do this, I'd be careful about who you choose to install this. This system was intended as a universal CC for a car.
BDF just figured out how to adapt it for a bike, and it works very well.
Labor time is money, and if it's the first time someone tackles this install, it can easily rack up 2-3 days of labor. Also, liability.
If you're like most of us, we prefer to work on our own bikes, for many reasons.
If you do your own, you'll understand it much better, and be more careful than a shop would be.
For me, the one part I had to be real careful about was drilling the hole in the throttle cam on the bike. One of the injectors is right behind this, and you MUST place a piece of metal behind the throttle cam as you drill to prevent the drill bit from going through the cam AND the injector!
Not a big deal, if you have the heads up first, and do this. FYI...
But, if you have some mechanical/electrical aptitude, you can successfully install this.
