Well I called Lexus corp not the dealer and they were abel to verify with the VIN that my vehicle is equipted with the "TO" option that has the upgraded alternator, Trans cooler and radiator. Thank you all for your help and direction.

I have a 05 RX330. I want to know where the "Lexus OEM Junction Block Assembly No.1" is located, not the plug under the cargo tray. here is a link to the part in question..... http://www.sewellpartsonline.com/parts_det...72896&all=Y

I think the only real way without taking the car all apart is to install the tow kit and test it, if i have power at the flat end plug and all my lights on my boat trailer work then im ok. or does the converter box do some other function? Should the dealer know from my VIN if the vehicle has the "TO" option?

Yes, i have searched for hours and have come up with nothing for the Lexus OEM Junction Block Assembly No.1 Part Number 82670-0E040 I have plenty of into and pictures on the hitch assem, thanks to this site for the install of hitch. so GDixon if you have any info on where burried in this forum where the location of the Lexus OEM Junction Block Assembly No.1 Part Number 82670-0E040 that would be greatly appreciated. One person said under the rear passenger seat but never confirmed that.

I have a 2005 RX 330, that does not have a factory tow bar/package on it. I want to order the "kit" that contains the hitch, 4 pin connector etc. http://www.sewellpartsonline.com/parts_detail.asp?id=87774 BUT it say some models not equipted with option "TO" have to have the Lexus OEM Junction Block Assembly No.1 Part Number 82670-0E040 http://www.sewellpartsonline.com/parts_det...72896&all=Y I can even find a sticker like the GM's that have the RPO codes on them. Where is this Junction Block Assembly No.1 even located to see if I have it on my vehicle already or where it installs to? I did check the Fuse pannel and it has the black marked fuse in place in the "tow" slot. I say black marked because all the other fuses in the block have a black sharpie mark on them as if they were checked from the factory. any help would be greatly appreciated. Thanks.
