Hi,
Looking at the schematic, this vehicle has signal relays for trailer towing. However, the vehicle signals are controlled by the body control module.
I attached a picture below showing what I mean. Let me know if that helps answer your question. Also, let me know what is happening.
Take care and Happy Thanksgiving.
Joe
