This is for the 1993-1994 unvented opti:
GM PART # 12106559

You're going to be unhappy that you lost the harness, because they are not cheap.

 

Just that one conector thats about 1 1/2 feet long?

 

Yep, the small harness that plugs to the opti and the other end by the RH side of the intake.

 

Man that sucks its like $90 well thanks for the help!!!!!!!!!!!!
Would you know any one that has a used one or somethin?

 

Maybe someone that has upgraded to a vented opti.

Call Jason or Dal if you need a new one. It will be about half that price.

You still need that harness? I just did the upgrade and will get rid of mine cheap. I know this post is a little old, but never hurts to ask.
