looks like you answered your question....
the options might make a difference in them.
and I would think the difference would be an upgrade

How is your search going? I have a 93 LS with TRAC and I want that harness you found if you end up not to use it. Please let me know when you are done with your search. Just send an email to me directly at moat@fossa.com

Also, where did you find that 93 LS harness with TRAC? Junk yard? How is its condition?

Which "engine harness" do you exactly mean? You are not talking about the spark plug ignition wire set are you? (#90919-22262 new oem for around $155-190)
