If that's not it, then I may need to find a main body ecu (front driver fuse box) from a left hand drive europe car.

Upon further inspection, the "caps" on those plugs aren't just caps. They DO in fact jump wires to each other on those male connectors. The other ends of these two cables terminate the same way with caps at the main body ecu / fuse box. This leads me to believe that it's possible these caps are different for different regions that have different tail lights or other features, with jumps in different locations.

As mentioned before, the fuse box is the same no matter where the LS460 was sold around the world. All I am looking for is someone with a 2007+ LS460 to post a picture of that connector.

The connector doesn't reach the fuse box and there are no open ports. It either connects to itself with a jumper connector, thus connecting wires inside the connector, some type of jumper harness, Y-splitter, or? I have all the Lexus workshop equipment and there is no external programming to enable the rear fog lights

Everything is already there. The fuse for rear fogs is in the boot fuse box, as is the relay, and all electronics. I really just need a picture of that white connector. I did a conversion on an IS-F without issue, for some reason this one is more complicated.

Yes, I spent about 8 hours trying to reverse engineer the wiring and looms as I have no access to non-US wiring diagrams or any other car to compare to. The front fogs work and everything else works properly. There is simply no 12v at the rear fogs at any time. Either the rear fuse box is not getting a canbus signal to turn on the rear fogs, or the rear fuse box is not letting that signal get through to turn on the rear fogs. Without knowing where that loose white plug goes or access to any wiring diagrams I'm at a stand still. The rear fog 12v wire ohms out at that open white connector, which is why I think that connector is simply left open in countries where rear fog is not standard, and connected or jumped to itself in order to enable it.

Hello, USA based here. I'm installing the factory rear fog lights on my US spec LS460. I have the correct wiper stalk installed and the rear fog lights, however the switch doesn't activate the lights. Everything related to the boot fuse box/bcm, canbus lines, wiring to the rear fog lights are the same for all LS460 models worldwide. I think I'm missing something related to these open plugs. Was hoping a member could take a snap shot of these connectors in the boot to see if they are plugged into something, or a jumper harness on a UK spec LS460 that I need to do in order to link the switch to the rear fuse box to the fog lights.
