Default reverse polarity effect

These are the two wires you want behind the factory dimmer switch although I don't recall which one actually dims:
Dude you just blew my mind, lol. SO one is power (yellow/red) and the other (green/white) has power too, bu the green white is neg dimming power?

SO green/white should be the neg
yellow/red power?

I tried to tie into the dimmer control for added foot lighting and got the same results as loose_electron reverse polarity, where the dimmer goes off when the rheostats/dimmer control is at it's brightest and viseaversa.
I do have mine ground to a ground. Maybe that's the problem and it should be grounded to the green/white wire?
