Vacuum Sensor/line hook up help.

The GTS charge loom should have these presumably. The VSV on the right is an aircon idle up and on JDM cars is mounted on the front of the right hand side (as you sit in the drivers seat) strut tower. The loom plug for this comes from the branch leading to the alternator.

The VSV on the right is a general idle up and on JDM cars has a loom plug situated low down in the right hand side of the engine bay near the standard airbox. In fact it actually mounts on the airbox in a JDM car
The photos in the post mentioned above are reproduced here with identical numbering. The throttle body you have may vary slightly. GTS ignitor/distributor wiring differs from JDM. Look for Will Drift for foods posts in the wanted to buy column for pics.

Picture 2 ? goes to the idle up solenoid you have asked about in picture 4 (with the green plug), specifically the end nipple, then the inner nipple line goes to the airbox on an AE86, or the I think to the intake tube on an AE82.

Picture 3: 4 & 5 are coolant feeds for the waxstat. 1 & 2 I think are for the power steering( block these off), 3 goes to the aircon idle up solenoid (picture 5, specifically the F [vacuum] outlet), the other outlet on this valve (e) goes to the airbox.

There is no point bothering with the two idle up valves in 4 & 5 unless you have the rest of a functioning idle up circuit. On an AE86 this is incorporated into the loom that includes the headlights and charge system from the fusebox in the engine bay around to the junction box in the drivers footwell, then across the car through various diodes within the dash loom to the ECU. Earlier 4AG AE86's then had an idle up computer (a black plastic box slightly larger than a ciggie packet) which clips on top of the ECU. I think later looms incorporated this within the ECU, and I think this was the case with AE82 twincams (?)

Having a functioning idle up circuit makes the car a lot nicer to drive in traffic. But you can get by without it.
