    99 Wrx sti no Front O2 sensor plug

    hi all members.
    Im new here,From mauritius and recently just bought a jdm GC8 wrx sti.
    So i noticed lots of carbon in the exhaust and inspected the o2 sensors,the rear is good and connected,but the front one got its wires cut and i cant find the plug.
    Also im getting check engine code 32.
    I need to know the wire colors(how many also),and from where the wires come from.
    Mine is a RHD.
    Regards
    I searched alot,but coldnt find anything that would help.

    Code 32 is a problem with the EGR system. The lack of the 02 sensor could be causing that. I'm confused why you're asking about the wire colors when the wires are still there, but clipped.....
