      Maintenance Repair. If you are experiencing intermittent check engine lights or rough running conditions it may be caused by a bad oxygen sensor harness. O2 harnesses are exposed to the elements and road debris on a daily basis and this could cause them to become damaged. So replace your malfunction harnesses with a brand new set from AmericanMuscle.

        O2 Sensor Wire Harness

        Ordering and shipped great, but not enough information on application for rear sensors. Hard to install on Automatic transmission, due to tight spacing.

        O2 sensor savior

        I recently upgrade the cams on my 96 gt, and must have disturbed my original harness, because everytime we put my car on the dyno it killed the drivers side o2 sensor. This new harness installed easily, and seems to have fixed the problem. You have no idea how happy this makes me!!!

      3 Top Rated Questions

      Are there two separate 02 harness on 98 gt? Right bank, left blank?

      • A 98 GT uses a single harness which splits, where one connector goes to the right bank and the other connector goes to the left bank. This OPR O2 Sensor Wire Harness has the split, so a quantity of (1) will be all that is need for connect both banks.

      i went under my 98 gt and there are no rear 02 wires where do these plug into?

      What about rear 02 sensors is that a separate harness.

      • The OPR O2 Sensor Wire Harness can be used with both the front and rear O2 sensors.
