Well more to my saga. I've got the harness off. I have to pull the whole fender off to get to the harness thanks to the Hidden hitch I have on there. I got the hitch for Xmas last year and instead of doing the work I'm doing now then, I wanted to see how everything works before cutting into the harness. Then I found out I would be having rotator surgery. So this is really the first I could get to it anyways. The EC units come with those taps and of course the solid way to do it is to splice and solder in and cover with shrink wrap. That makes it permanent, no wiggly bits.
Another problem with the Electrical Connections setup is it is designed for open stem turn signals. You have to run wires through the stems to get to the LED units. Well while some units have hollow stems the Kawasaki 900 units have a waterproof plug midway thorugh it. And the socket for the lamp fits the only opening snugly. You have to grind a pathway into the housing for the wires to run through and this is almost always to shallow causing a pinch point in the light assy. Now, while that could cause an opening in the wire, generally it hits against the side of the sharp side of the socket and grounds the wires, always the power side too. That'll blow the fuse I can tell ya AND it blows the diode assy that comes with the kit. It is ingenious though. The leds take power from the headlight and ground through the blinker bulb circuitry. While the bliinker is off there is power through the LED units but put on the brake light OR put on the blinker and that leg of the circuit now has the same voltage as the normal power. Without potential the leds go out. So when my bulb stopped working the potential voltage was still there, so the led unit did flash and operated normally as a running lights.
All this muckity muck and drilling, grinding, shorting, bad connections can be avoided by using the plug and play, swap the lense method of the Kury unit. PLUS you don't have to cut in a separate brake light modulator. When I first asked the question you asked it was after I had found out about the brake light modulator and had installed one. Separately they all add up to more then the expense of the Kury unit.
I suppose I could recommend the Kury unit harder, but I just don't know how.
