Hey guys, I'm hooking up my vacuum lines on my TBI swap, and had a few questions. Figured since a few of you are TBI, you could probably help out. The first question I have is on the back of the intake manifold. There is a small silver Hex screwed into the manifold with a vacuum port and hose attached. What does the other end of that hose attach to? The other is cruise control related. In the cruise control harness, there is a large vacuum hose. Where does that attach to on the engine side? The interior side connects to the brake switch. I thought it connected to the cruise control servo, but it seems too large in diameter. The next one is on the MAP sensor. I have a vacuum line from the TB to the map sensor, but on the MAP sensor, there is port, but nothing hooked up to it. Should there be something hooked up there or is it open? The vacuum ball...where does its vacuum line attach? Last, but not least, the climate control harness coming out by the heater box has a vacuum hose, where does it attach to? I really wish I had taken more pictures when I tore down my 87, dangit! I looked through my factory manual, but couldn't find anything really. Thanks!
