Ok.. my o2 sensor (WB) is currently connected to the EMS. It is installed in the O2 housing and have replaced the stock sensor. If I replaced it with the stock, I know I need to connect to engine harness, but where is this usually located?

B. To swap the O2 sensor in the front, what is the easiest way to access it? Someone told me i have to remove the raditator. Is there an eaiser way w/out removing big parts to get to it?

The O2 sensor connector is under the spark plug cover on the passenger side. I never swapped out O2 sensor with the turbo in the car, so can't help you there.
