        Is this harness compatible with all 87-93 manual transmission cars? I know there is differences in the factory harnesses from year to year and can cause issues with the ECU.

        • The OPR O2 Sensor Wire Harness is designed specifically for manual transmission 87-93 Mustangs. This will not present any ECU issues.

        Does this harness include the low oil sensor harness that is in the factory o2 harness?

        • actually based upon the pictures it looks like it does include the low oil connection as well.

            Great upgrade

            Great upgrade and replacement for the old malfunctioning harness on my 86 GT. Allows you to upgrade O2 sensors along with this harness while doing a computer upgrade to mass air conversion.
