Trailer brake lights stuck on.

Sorry not when I pull the relay but when I reinstall it. Hold up I’ve been tracing ABS power. Let me back track some.

 

the ABS relay isn’t marked at all and there is only trailer tail light relay which it checked out ok.
I was just going off of what relay was turning the lights off. The other relay called “trailer tail lights” wasn’t turning off the lights and I couldn’t find any other relay that made sense as to what ran the stop lights anyway it all makes sense now!!!
Once I figure out I was on a wild goose chase I started over and got it fixed now. A rookie mistake!!!
Turns out a wire was in the wrong spot in the junction box at the back of the truck for the trailer. I don’t know if it has been routed this way ever since and my driver just realized but I’ll attach a picture.

Anyway thanks for the help! You questioned that abs relay and made me stop and think about it. I should have known that red was stop and blue is ABS but I wasn’t thinking.
