Hi, The first item is, which O2 sensor? there are two of them so I'll give you both. As I look at the schematic I can see the O2 sensor #1 is Pink and Red/Blueink goes to D19/C23 Red/Blue goes to B8/A2. O2 sensor #2 has Yellow or Red/Blue (it can be either or) and Pink/White or Pink/Blue (again it can be either or). O2 sensor #1 is at the manifold and O2 sensor #2 is by the Catalytic convertor. I avoided the confusion by purchasing the ones with the plugs attached so I don't remember what the price difference was. I hope this was in time for you and good luck. Steve H.
