Harness came off of an 83 Trans Am I had in the early 00's.  Pulled the injection system for a different project that was never completed, and I have finally given up on.  The harness was in good working condition, but has been stored almost 20 years, and hasn't been tested recently.  I couldn't find any visible defects, but it's possible that I missed something.  It's being sold as is, and may need repair before installation.
