So as it turns out, Brandon Distributing has shut it's doors. Now that it's played out in that direction, I have a few things I wanted to say.
The cruise system that I have up to this point isn't 100% perfect. I think the problem exists somewhere in the wiring harness, since the crimp connectors and solder joints are not exactly the best. Some of the wires also have small nicks in them, which could be part of the issue. There are also some missing wire seals, so some of the connectors aren't water tight. For something I put on my own motorcycle I think this is unacceptable (for a testing unit, it's fine). In my testing, I was able to get the cruise to work as expected, but about 2 out of 15 times I tried to set my speed, the check engine light would come on. The light would shut off after about 30 seconds, and the cruise worked just as intended, but obviously a CEL isn't wanted on a production quality system. I never experienced any kind of limp mode or anything, so at least that's a plus.
At this point, I urge anyone who has sent him payment to contact your credit card company and have them issue a chargeback.
Now, I still am dead set on getting cruise working, and getting something to market so everyone here can benefit. I've sourced all the connectors in Joe's harness, and am certain that it can be produced. As for the cruise control box, it's a Smart Line AP900C. This is a generic unit that comes from overseas, but it seems Joe is the only distributor in the US. MC Cruise out of Melbourne Australia also carries this unit. I will be trying to contact them to see if I can get them to pick this up where Joe left off. This is because while I have a functional unit, you can't just buy an AP900C off the shelf and plug it into the harness. It needs to be programmed, and I have no clue how to do that. I'm hoping MC Cruise is able to pull the configurations out of my unit and start from there.
There's a thread over on the ADV Rider forum in the KTM 1190 section that's a really good read if you all are still interested. Joe was orginally the one to help create the first working system, but MC Cruise has apparently also entered the market for that bike, and reports seem to be that theirs is more reliable.
I've already been contacting electronics distributors to try and buy all the connectors and wire I need to try fixing all the problems I have with a new harness. This would be just to get mine more functional, I hope that MC Cruise out of Melbourne can get a working unit ready for sale, so more people can enjoy cruise.
