Just bought the van, owner said it was timing chain, it wasn't, he overheated it blew both head gaskets , long story short, i just finished fixing and buttoning it all up except daaaaa , i have a vacuum port missing a vacuum line and the box bolted on top of the left side (front) valve cover that has a cable that runs to the secondary intake ports is also missing the three wire plug, well question, does anyone have a vacuum diagram for where that hose comes from and also the plug for the secondary intake port controller? oh the vacuum port is in the front side 1/2 of the intake manifold drivers side pointing to the battery , pointing horizontally and 3/8 diameter approx.
