Agreed! I designed a time-based system for the Honda Valkyrie. Am working to add the distance factor to it, but too many other projects! As it is now, it's been working great for a few years and very intuitive. Having the Hazard/Escort Flashing is a major plus!
The core design is universal, in that, it can be used by any type of motorcycle that has the standard mechanical left/center/right Turn Switch design. The plug/play aspect is the tedious part because the wiring harness that adapts my unit to the motorcycle has to be specific. LUCKILY, motorcycle manufacturers tend to employ the same wiring pattern across many models.

That's why I'm seeking help from the Triumph community. Basically, I need good detailed photos of certain plugs. For the Thruxton/Scrambler/Bonneville series, I need closeups of the plugs going to the Turn Signal Switch and the Instrument Cluster. Pictures need to show both Male and Female sides of the plugs and the wiring placement and colors. That's VERY important. With that, I can verify how to build the plug/play harness so the wires are properly linked to my unit.

For the liquid cooled models, you need Sumitomo 2.3 mm unsealed auto connectors

Here's lots of pictures

Thanks! Yes, familiar with the Sumo's. Years ago I did try the STS system and wasn't pleased. It's actually what led me to designing my own... improved on the design and functionality.

Sumo makes a number of connector types which can vary among models series and location on each bike. Because of this I need specific photos of those circuits my design interfaces. For the Triumph's that always includes the left switch package (HM series you referenced or HD depending...). The other circuit I need to interface is the Instrument panel plug, which seems to usually be the Deutsch DT series and can either be one or two plugs depending on the bike model. Even more critical are the exact placement of the wires within both sides of any circuit. My unit is total plug and play, so all these details are critical. But oh how sweet it is to install!! No cutting, no mess.

Thanks again.

Other times I have been distracted by something, like cars potentially pulling out in front of me, that just caused me to just plain forget. It doesn't happen that often and I don't think I am that unusual or incompetent of a rider. But I'd venture it does happen on occasion to most all of us mere mortals. If it has never happened to you, which I will agree is possible, you are indeed an exceptional rider. Another scenario could be that it just doesn't bother a rider if he found that he rode for miles with his turn signal on.
All the time... all the time. And I feel like a newbie everytime...
