I have a new Curt T-Connector wiring kit for RX330s and 350s that do NOT have the factory towing package. I had installed it but never even put the power to it. I had realized after the install, I already had the towing package from factory, so thus, I chose to purchase the OEM wiring harness instead.
As you can see in the pics, it is like brand new. I neatly re-packed the kit just as it came out of the box. It is literally a few days old.
I'll take just 40 shipped for it...2-3 day delivery.
If you eventually are going to install a hitch on your non-towing package equipped RX, here is your best bet for a deal right now. This is what you're going to need.
Email me if interested.
Thanks!
