Thanks for your thoughts! I understood there is a brake controller wiring connection under the dash - so I assume that's what they attached to. Can't imagine where it went wrong. I will also talk to the travel trailer repair shop this week to see if they can figure it out (so far they've been great). Thanks again!

So Colorado Springs Lexus REFUSES to put a Brake Controller on my '04 LX470. I end up driving to Denver (160 miles round trip) so that they can install it. I get back home, hook up my travel trailer and to my surprise, my rear window wiper kicks on for 5 revolutions and then stops. Ok, I guess I could live with that, but then, the interior fan goes on - even without the key in the ignition! So now I'm unable to park my trailer without unplugging it to prevent my battery from going dead. Just for yucks I hitch the trailer to a friend's '01 Dodge Durango - Walla, no problems! So I'm wondering if it has anything to do with the Brake Controller, but instead may be the hitch wiring on the vehicle? Any thoughts on correcting the problem without a drive back to Denver?

Bruce - Did you ever find someone to help with the Brake Controller? I have an '04 and the Colorado Springs Lexus Dealership refuses to install one. Hard to imagine that the vehicle is rated to tow 6500lbs, but they refuse to install a legally required controller. I also called the 800#...they told me to try U-Haul to get it installed!!!!!! Bxstr
