Is there a fuse for trailer tail lights?

[Finixoid]

My 2010 LX570 didn't come with the trailer wiring harness. I installed a 7 blade one from ETrailer that had to be connected to the driver side socket. Everything except tail/marker lights on the trailer works fine. What can be wrong, is there a separate fuse just for the trailer tail lights?

yes there is, 30a and also appears to be a relay. If you pull the fuse box cover in the engine compartment you can see the diagram with the locations.

I have the same issue discovered this weekend, everything works except the tail lights.

It worked. I found that fuse and replaced it. Everything works now. Thank you!

curious if you check for power at the relay? if so do you recall what pins had power under what circumstance (switch position)

No, I did not check that. I saw the fuse was blown, and just replaced it.
