Need help identifying some wires (05 EC250)

Tonight I stripped the my bike down a bit. I want to do some cleaning neglected by the previous owner.

I also would like to add back a headlight as well as a tail/brake light.

Under the seat I found this wire. Yellow, violet and white. I believe this is for a rear tail/brake light?

Then I found these bunched up in front of the gast tank. Two yellow and two violet wires. One pair has "aftermarket connectors" as you can see they're the ones my thumb is holding. I'm guessing possible high beam/low beam or turn signals? If they're turn signals where I my darn headlight wires.

Then I found this cluster of wires as well. I know the round black pieces is the coil. But I have no idea what the smaller black square box is. Everything is connected, so I think this part of the wiring is fine.

Top one looks like the rear brake light wires. The second looks like the headlight wires. The black box is a rectifier.
 
Why not just use a simple toggle switch. That is what my bike has. It is mounted behind the number plate and probably costs $2 at radio shack.
 
That could work. Partly I was hoping to try and get this road legal. So having the extra functions available on the switch would be good.
 
Follow up....

So I received my new Polisport headlight today.

The back of the headlight has 3 prongs for the headlight. There is a second set of wires (two wires) for a bulb that is offset to the left. From I have found this is a Euro requirement? Here is a picture of the back of the light.

Here is a wiring diagram I found for the 3 prongs on the back. The headlight came with nothing.

With the wires below...what would be the property way?

I would recommend a "marine grade" 3-way toggle switch. I used them on my off-road only 4x4s for years. Switch in the middle, "off". Switch in down position, "lo-beam". Up position, "HI-beam". Cost: under $20. Just a thought:D
 
Switch I'm all set on now. I'm confused for the wiring. On my ATV's all I had to do is find a hot wire when the key was on and run a ground.

Now I have 4 wires on my bike. 5 wire connections on the headlight and I have to wire in a toggle switch as well. That's where my confusion comes in.
Just a thought...Do two of the wires go to a switch? The other two run to the headlight? Then I just need to run a ground?

As for the extra light on the left...the DRL...I could just leave that disconnected. Or feed it power from the main light?
 
Try this for a wiring diagram-

Since we don't have batteries on the old models, you have to hunt for hot with the engine running. Also, I don't know if you have a regulator/rectifier or just the regulator. You may be running AC instead of DC if you have the little two wire box. I have a trail tech reg/rec standing by for the day I convert my '02 to street legal, but right now I am running my headlight on AC power. No burnt bulbs yet, but it's only one small lamp. Just an FYI that it may not be as simple as we wish.
 
How do I tell if I have a reculartor/rectifier? My bike is an EC 250 and it had a headlight at one time.

The regulator has three wires, one to ground and two to yellow (I think, at least one is yellow). Reg/rec has more wires, I think four and is larger. The little regulator is tucked in the frame gap at the steering head, under the front of the fuel tank. If you have a fancy voltmeter you can test for AC or DC on the output. AC is regulator, DC is regulator/rectifier. In your second pic down, there is a yellow wire sheathed in black. I believe that is your hot to or from the regulator. I don't think you would have a DC rectifier if you don't have tail and turn lights, but I could be wrong.

The violet connects the front lights to the back lights, it has no power until you hook it up to power through the switch. It's confusing at first, but very simple once you figure it out, sorry I can't explain it very well. Grab a soda or a cup of coffee and stare at the wiring diagram for a bit. No beer, because you need (at least I did) your faculties when sorting it out. But, here's my interpretation- The yellow is hot to the switch. Violet is switched power out of the switch (provides juice to front and rear light systems). The white supplies switched power to the brake light from the brake switch, brake switch needs power from the yellow or violet wire, your choice. That should sort out your wires.

In a nutshell, yellow is always hot, and purple is hot when you connect it to yellow with the headlamp switch. White is hot when you connect it to hot through the brake switch. Clear as mud?

Here's a reg/rec-

Here's a regulator only-

Thanks Phil. I will take your advice and stare at that wiring diagram. According to Eff, I have a rectifer, if you look at the second picture I posted in my first post.
 
Coming back to this picture...there's 4 headlight wires...can one set be wired into the DRL light? then the other two wired to work with a HI, LO and off switch or is one set the hi beam and one set the low beam?

Upon closer inspection...I do not have two yellows and two violets. I have one yellow...which to my understanding is the hot. Another Yellow/Green which I believe is a ground...and two Violets.



Does that make more sense to anyone?
