Vacuum Sensor/line hook up help.

Sounds about right. There will be two larger tubes under the throttle
body for the power steering idle-up, and possibly two for an air-con
idle-up. Main thing is to make sure you block off any tube that sucks
in air when the engine is running. Don't loop the idle-up tubes.

A tube that is not blocked off will act as an uncontrolled air leak, and
any air leaks into the manifold will push your idle speed up.

Don't know about the O2 sensor, but how far wrong can you go with
only one wire ?? Try it and see if it throws a fault.
