Bump.... I'm still looking for info on the location of the junction box assembly. The only thing I can find is this picture, which appears to be somewhere around the rear license plate. Not sure if that's in the rear trunk door, or the bumper, or what. The junction box assembly is item 82670A in the pic below (located in the last "L" in "SEWELL").

I went back and rechecked everything...I did end up needing a Block Assembly, Junction Part # 82670-0E040. I changed out the block it had, it looked identical however now my trailer lights now work. After finding the parts on ebay and craig's list the whole thing...OEM hitch and junction block cost me $250. I did not pay for any labor and everything was easy to install. :D

I know this thread is old... Anyone know where the junction block assembly is located? My 2005 RX330 does not have the tow prep package.
