Brake Light Wire Location in Driver Kick Panel?
Hi everyone, just had a super quick installation of a pioneer stereo in my '04 RX330 thanks to all the posts on here. Encountered only one hiccup, could not locate the brake wire by the driver kick panel. I need it to connect to the stereo's reverse wire to start the backup camera whenever I go into reverse. I found some wiring information else where but could not for the life of mine find this green to red wire mentioned:

Thanks! Just did it and it worked like a charm. Getting to the wire was pretty tough since it was in such a tight spot. Alright, onto to the next project.

Solved!
I realized today that tapping into the brake wire would not be the best idea. Since the backup camera would be activated every single time I stepped on the brakes.
So I decided to take a picture of the other end of the gray 20 pin plug with my phone since it was impossible to view. I found out that the reverse light wire is the furthest left dark green wire, not the light green wire. And the view underneath confirms that it does go from green in the 20 pin plug, and out as red into the receiving wire harness.
I posted some pictures, so hopefully this helps someone out.
