Does anyone know the color of the GTS high beam head light wire color?
I'm installing CustomDynamics Headlight modulator on my GTS and I don't know if it is the brown wire or the purple.

If you have a multi-meter or a test light you should be able to find it without a problem. You can often find test lights in the $.99 bin at AM/PM! Connect the aligator clip to a ground point somewhere and then turn on the high beams and poke the sharp tip into the wires, if the test light lights up you have found it. Just to confirm, switch the high beam off and on to see if the test light turns off.... Be carefull not to stab yourself with the test light, they are often very sharp!

Here is the one I went with http://www.comagination.com/ it was "plug and play".

I did get the Custom Dynamics "Back Off" tail light mod. It works great.

Ooh, poking through the insulation, even in a protected area of the scooter probably isn't a good idea. With a little dampness or dirt you can easily get a "voltage creep" from the puncture to another wire or anything metal. I've not seen it on scooters but have on aircraft wiring. Try to measure at connectors, cable ends or fuse blocks when possible.

We all have different areas where we seem to be purists, this one may be mine.

Very good point, removing the headlight and checking at the connector would be best since this area might be exposed to outside elements some how someway. I use dthis technique for years though doing automotive electronics, but everything was inside the car protected from the elements.

I LIKE THE IDEA OF THAT PLUG AND PLAY MODULATOR!
