I just got done removing the back set in my RX330 and found this junction box.

Are there different versions of it?

The trailer hitch connection is plugged into it as well as other connections but no power.

I have a 2004 RX330 that I just installed the lexus trailer hitch on. The factory wired 4 prong connector has been connected but it is not providing any power to the hitch wiring. This is the same issue Steve Ross was having.

The fuse for the Towing option is in place but I don't think this has anything to do with power not being applied to the connector when the tail lights,brakes or signals are active.

Is there something else that needs to be connected for the factory harness to be active?

Thanks
