i think the gray is positive. i mnight be wrong. take a multimeter to it and find out.
and you might be able to hide the rocker into the little "change" hole under the dimmer on the left side of the steering wheel.
or maybe drill a little hole on the underside of the plastic under the steering wheel. (like, above where your knees are)
throw the rocker in those spots if you don't want it noticed.
if you start getting crazy w/ stuff, i'd suggest making a switch plate and mounting it somewhere... but thats me.
oh, and WOO WHOO you got cathodes!

i'll be excited for you.
