Hi guys, I've got two questions that hopefully someone will know the answer to.

I just finished installing a new wiring harness on my '84 245, and I'm trying to tie up the loose ends.

1. There are two vacuum plugs on the intake manifold that are angled toward the engine block. I do not know what connects to them or where they should go. On the manifold, they're right above the larger hose that connects to the idle air bypass valve.

2. There's a smaller-gauge black wire at the alternator that I assume needs to be connected to something. It comes out of the harness with the red wire of the same gauge. I don't want to miss a ground have a small engine fire upon startup or something.

I appreciate any answers. The harness was a process and I'm very close to getting this car back on the road.
