hello peeps, please help,.. ive just brought some new dials off fleabay and they are abit confusing, but thats not really suprising as i know nothing about wiring etc. they are backlit so obvisouly need a power source, the links below are the pics; http://www.dropshots.com/motormadj# it appears to have two powers [ the black and the red ] or is it just the red? if so where should the black go? should they both go on the live? and on the actual vr6 loom what is the live/power? is it black or purple, as there is no red??? please help, thanks
