Does anyone know which pin coming out of the ECU is for the O2 sensor? I grabbed the O2 sensor connector and the wire broke off the connector on the ECU side, and the wire sticking out from where it broke is too short and hidden under the intake manifold so im going to just use a new wire and route it from the ECU to the O2 sensor but idk which pin it is, all i know is that it should be a grey wire? help please thanks!

 

Pin 2C on the B1-22 connector.
