Innovate Mtx-l replace front O2

[sleakwrx]

So while installing my new 20g setup and EWG I pulled the front O2 sensor to be able to unbolt and drop the exhaust manifold on the passenger side. In doing so I think I broke the sensor or it got some coolant on it. Now my stock O2 reads erratic in the AP and I get the P1153 CEL. I know it can be one of two things either I have an air leak in the system or I need a new O2. Judging by the fact that it reads sometimes and then "fails" high I think its the sensor. I know my Innovate MTX-L can simulate the narrowband of the stocker but I'm not sure of which wire (brown/Yellow) to hook up or even how to make this work. If anyone has done it please let me know. Also if it can be done how badly will it trip up the ECU if its taking its reading post turbo instead of in the header? Thanks for the help everyone. BTW I'm in an 08 WRX
