I can, but I didn't connect it to the ignition phase simply because I have no idea where it is. You run the risk if you leave them on when turning off the engine, the battery will drain. I personally always look at my bike when I walk away. Also, I didn't solder the wires together but used terminal blocks. An electrical engineer will cry his heart out, but the way it's connected is correct. Just make sure you isolate and keep water out of the blocks.
- 0.75mm² wire.
- Bison rubber seal tape.
- electrical isolation tape.
- a few terminal blocks.
- tie wrap.
I'd advise you to solder the wires together, but I'm a man of change and a terminal block are quicker to dissemble and just really easy to connect wires.
I already have my USB switch on the left side, and the wires hidden inside my left pannier, so I used the right handlebar side for my new switch and hidden the cables inside the left side pannier too, where the Traction Control button sits.
*I layed a new wire from my battery to the break hose, via the pannier side and connected a terminal block to the end of it. Be smart, and connect a fuse between the positive wire and battery.
*I then connected one of the two positive wires of the switch to the block. The other has to be connected to the positive wire of the wire that runs to the lights. The negative of the lights wire went into the negative spot of the terminal block, creating a loop.
*Now, you have two lights, so that light wire goes down and splits into two. I again used a terminal block. The two positive and negative wires of the lights, I put together and inserted into the last terminal block.
Isolate everything properly with rubber seal tape. It stretches, and as soon as you start to wrap it, the material merges into it self, becomming vulcanised and 100% waterproof. I use this for my garden wires as well.
Not how most people would do this, but it works.
