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.

One of the vacuum lines probably goes to the ignition computer mounted by the WW tank.

Oil pressure sender wire...trust me, the sender is down there

One probably the flame trap and the other is likely the climate control vac...been a while since I worked on something that old.

Hope that helps.

Thanks Onkel, that solved it.

I forgot...by law, there is a vac line diagram under the hood (if it has not been removed) as part of the emissions diagram.
