Can somebody provide a wiring diagram for the best way to wire fan with dta s40 and also a override switch so i can operate it manually?

Use a relay exactly as shown in the S40 diagram. if you want to add an override I suggest you add a switch to ground to pin 18

I don´t have the wiring diagram to follow but i get what you mean. So the Ecu basically switches to ground and has 12v supply to the relay coil all the time when ignition on. So just need to take a tee off of the Relay coil negative through a switch to ground.

Yes, and as Alex linked, DTA pinouts are readily available online
