Does this wiring seem wrong to anyone else?

2025 Ford Transit 350 HD 3.5 was sent to the dealership to install a tow package. I got it back today and noticed the 4-pin connector dangling by a zip tie. I follow the wires into the back of the van and find that they just crimped the 4-pin connector into the turn signal wires. Now I know it will probably work this way, but that cannot be right.

I’ve worked on transits before they all have a trailer module on the driver side b pillar that controls trailer lights. My transit doesn’t have one installed. Does it need one? Do I take it back to the dealership?
