Well, I finally got around to installing my "bargain" harness due to driveability problems last weekend. I am actually amazed that the car ran at all amd as well as it did. The old harness was swiss cheese, cobbled and taped. I did have to get 2 connectors off my old harness, the Idle Control Valve connector and a gray connector I have no idea what it is. The new harness is in great shape, still had yellow attachment tape and part number sticker and all wires in like new condition. I went ahead and removed the intake manifold and TB to clean them. What a dirty mess that was. Anyway, I installed the harness one night the next I got the manifold and TB back on. Started it up and it idled at a very high 3000 rpm. Based on the archives I looked first at the ICV and it's connection. The connector from the old harness did not have the same color coding as the harness (repalcement) so I could have possibly wired incorrectly. So with the car screaming like a banshee pulled that connector and it settled "somewhat" at 950 rpm. As soon as I would touch it to the ICV screaming would return. I pulled the valve and am in the process of cleaning it better and I am going to check how the connector is wired.

Bottom line is, I am almost there and even with it's present irregular idle it is worlds above where it was before. And it's much quieter.

Thanks to all who chimed in and especially Mr. Barton for calming my fears.
