When I go to turn my parking/marker lights on my headlights turn on also. I have check over all grounds. This only happened after swapped out my fenders. Is there a ground it connection I may have missed? If so would anyone know where it is located?

Not sure if a ground would do this - and if so - I wouldn't know where to look.
However, it might be your dash (pull / push) switch has quit operating correctly?

Switch and connector are a known failure point. Check for electrical/burn damage. Do you have higher power than stock headlights, by any chance?

The only way for the fender replacement to cause this would be if the DRL wiring is pinched.
