That was a very clean install. How long did it take you to round up the spare harness parts, and do the actual installation?
IF I knew everyone was as capable as you, I'd feel comfortable making stuff that wasn't plug n play. But most people really suck at wiring. There have been many times I was asked to check out a customers bike to find wire nuts in the ignition wiring. I've seen people cut the battery ground wire off for weight savings. There are a lot of reasons I would never recommend people to do stuff as complicated as the installation you did.
Then there is the satisfaction thing. If I spent $500 on it, I hate having to spend another couple of days trying to round up parts to get everything to install properly. I like to pull the piece out of the box, have all the parts needed in the box, and have it on the bike as quickly as possible. I design my electronics like that , I wish the rest of the aftermarket would do the same.
I purchased an entire wiring harness from ebay prior to buying the Motty unit, the wiring harnesses are available from people that replace the stock harness with a race harness (no lights etc). I got the ECU connector from a company sample ,however I have also obtained them, very cheaply, from smoked ECU units on Ebay. You are right that part is a bit of a pain. The actual install took about 5 hours (and 5 beers) going very slowly and double checking every wire.
I wish the rest of the aftermarket would make everything plug and play too. In fact I almost passed on the Motty because of the non-plug and play issue. I spoke with the owner of the company and asked about the possibility of PNP. The issue is that they are a small company and all the motorcycles that the Motty uint can work with represents a multitude of connectors. Honda uses a different ECU connector than Suzuki and Yamaha uses yet a third. The 600s in some lines have a different connector than the 1000s.
I researched the development of a PNP solution to market for the Mottyand I found it was just too expensive. Because the connector manufacturers require a minimum number of connectors to be purchased at a time and then that is multiplied by the number of bikes to build it for and you can see how expensive it could get very fast.
The reason I ended up purchasing it is becasue it really is the best solution for real time auto tuning of a motorcycle which is the units greatest strength.
However the real time auto tune capability requires mutliple signals from the ECU that the other units do not require thus making it a more involved install.
If you think of a way to make it PNP let me know, I believe there is a huge market potential for these units if PNP beomes a reality.
