Little help pleas. HANDLEBAR HEATER.

[gregk]

I have a heater i never fully hooked up. Its one of those paper ones that lay on the handlebar.  That I had done, with the wires going through the handlebar. 3 wires for low heat and high heat Red, Green, Blue.  I also bought a toggle SW. (on/off/on) And I have a hot wire for supply to the SW.   How do I connect the 3 wires. Thinking one must be a ground, right ?
   If so I should be able to do a resistance ck across the wires to find which one goes for the high heat and whicn goes for the low heat right?

Rule of thumb (?)  green would be the ground.
