After a lot of research and fiddling around, I got this together.
Once I figured out a key point (all the wiring is in the headlight), the rest of it got pretty simple.
I do wish there was a really good page on this someplace; I guess I have to make it.
What I wound up doing was to buy a pair of really cheap, crummy turn signals at my local Cycle Gear shop, just to get it going. I cut the OEM connectors off my stock turns and wired 'em onto the cheapo signals I got (the quick and sloppy way, twisted the ends and taped 'em up).
That worked for the short term just fine.
I wound up mounting them on the sides of my fairing (The 'cafe racer' bikini fairing from Bella Corse, IE, the Emgo Viper), using the existing screw holes so I wouldn't have to make any new holes for the time being.
Meanwhile, I ordered some LED lights from Joker Machine when I bought by ignition relocator.
The thing that got me was that every site I checked said something different about the wiring. Joker said I just needed to wire in a 'diode kit' from Küryakyn, where the other sites I checked (custom dynamics and others) said I needed a load equalizer. It took me quite a lot of reading to figure out there are two problems with LED turns.
- first, there's the idiot light issue. Since the Bonnie had one idiot light, with both sides wired though it, LED lights will typically cause both sides to flash together, because of the lack of electrical resistance. That's what the diode kit is for, but the diode kit requires some cutting-and-splicing of wires that are frankly kind of hard to get at.
- Second, there's the 'fast flash' problem (your turn signals will rapid-flash), because, again, the stock relay won't see the low-resistance LEDs as a load on the wires. This looks the same way it'll look if you have a turn signal bulb out.
I was somewhat stumped about this, because the solutions seemed both expensive (the load equalizers get up near a hundred bucks, at least for the ones recommended by Custom Dynamics), and required some wire surgery I didn't really want to do.
It wasn't until I grasped the parts of the problem that the, pardon the pun, lightbulb went on over my head.
What I realized was that both solutions were easy, and readily available.
The idiot light is neatly solved by the 'idiot light kit' from New Bonneville; not only does it get me nice bright idiot lights, but it also serves the same purpose as the diode kit, removing the 'all lights flash' issue, a feature of a mod I already was going to do.
The relay is easily solved by replacing the stock relay (under the left panel; to find it, just follow the click!), with fairly standard relay, the K&S 24-00005. Said relay can be ordered from Amazon, or from Biker Highway, and is the exact same one Mike offers at Bella Corse:

Wiring for the rears could not have been easier, because as part of this I put in a FEK from British Customs, which has the advantage of having a complete plug-and-play wiring harness; I just crimped bullet connectors to my new rear turn signals, and plugged 'em into the appropriate connectors on the FEK harness (Using the aft relocator brackets from NewBoneville.
I'm really happy with the result, and the whole thing couldn't have been much easier, once I figured out what the hell it was I needed to do.
