Does anyone know what color the dimmer switch wire is? I cant figure it out so I'm hoping someone knows.

i would have to look at schematics. you can tap it off the ISO fuse (18 IIRC). you could use a test light to probe wires at the back of the headlight switch too. when you have the right one, the test light will dim with the dimmer.
good luck.
