They say that you need to leave your OMP plugged into the wiring harness.

 

If the pump is dead on an S5, you can't just use a block off plate and leave it plugged in. The ECU will continue to throw a code because the pump isn't working. You will have to buy a new pump.

The people that use a blockoff and keep the pump plugged in off to the side, have working pumps.

 

if ya buy a rtek chip you can leave the pump unplugged.
