I just bought a 2005 RX 330...it does not appear to have the towing prep package...I can't find any wiring behind the bumper...I can find lots of trailer hitches but no light conversion kits...is the dealer my only choice?

Anybody out there have the factory installed trailer hitch? We're trying to find a picture of the factory hitch and the Lexus website only has a close up of it so you can't see how it fits around the tail pipe. If you have the factory hitch and can send a picture I'd greatly appreciate it. You can send it to kerberkmaol.com. THANKS!

Even if your RX has the towing package, extra ATF cooling, it probably REQUIRES the extra ATF cooling for normal operations and so there is no EXTRA cooling provided for "abnormal", towing use.
 
This appears to be especially true for the RX330 series as the factory recommended maintenance schedule for ATF flush/refill has been revised downward, from infinity to every 15,000 miles.
 
At only 40,000 miles the ATF in my '01 RX300 was quite clearly BURNED, I assume due to being overheated. My '01 has the towing package but I removed the hitch the week I bought the RX and it has not endured any level of heavy or seevre duty, at least not by normal standards.

Mine is leaned up against a tree out in back so I'll try to get you a quick snap.

Your RX330, and all later RXes, makes use of DBW for a myriad of reasons but the primary one being to "protect the drive train". The "abolition" of the old style ATF line pressure pump with the introduction of the RX in '99 resulted in the transaxle not having the capability of completing a second gear change in quick sucession to the previous.
 
With your RX330 you are likely to encounter 1-2 second re-acceleration engine torque delivery delays as a result of this drive train protection measure.
