the harness on the top of the engine on the passenger side. one goes to the opti unit and the goes???? to the computer i'm guessing??? is their another quick disconnect or is it spliced directly into the computer? the reason i ask ask is because a rabbit chewed through that wiring harness a few years back. as a fix i just spliced the wires onto each other. but now that i am replaceing the opti with the MSD distributor i'm wanting to replaced the jacked up harness. does anyone have info on this?

According to Shoebox's wiring diagrams, there is no connector between the test connector on the side of the intake manifold and the PCM.
