Diagrams.

[JasonBates]

Can anyone point me in the direction of getting vacuum and wiring diagrams for an M10B18. I can't seem to figure out my vacuum lines.

The PO was an idiot.

IDK about vac, but here's a great wiring diagram resource for early e30s.

That will work great. Thanks.

Now, I just need to find a vacuum diagram.

[irish44j]

vac lines aren't that hard - what are you having trouble figuring out?

Here's a pic of my non-bling bay, in case it helps

[JasonBates]

A few more pictures of where the vacuum lines go to and from would be great. The PO thought it was a good idea to remove all of them now I have no idea where they all go.

Vacuum line going directly from the intake manifold runner upwards goes to the brake booster. Off the ICV going to the right, it goes to the intake tube. Under the Cold Start injector there should be a nipple (on an 85 that's where it is), that vacuum line goes to the fuel pressure regulator. The small line coming off the throttle body goes up to the firewall, there should be a small vacuum module there. That module goes to the distributor advance diaphragm. Sorry, don't have pictures right now, but I hope that helps...a little

*Edit* Alright, I'll jump on that tomorrow. But I have this thing on my firewall that pulls vacuum, and I have no idea what it pulls on.

I just don't know which side goes to where.

Is this module? I want to make sure we're on the same page.

That is for the distributor.

[JasonBates]

That is for the distributor.

Where does the line from the distributor plug into?

[Farbin Kaiber]

Vacuum advance solenoid

Awesome! Thanks guys.

I'll let you know how it turns out. Hopefully this is all it needs to run.

[irish44j]

I'd post more pics, but it's almost impossible to take pics of the lower ends of the lines.

In my original pic, a couple of those lines go to the elbow below the throttle body, and another one goes to the power brake booster (use a reinforced line for that one, especially). If you check out the realOEM diagrams, it will give show you where most of them go. There are various ways of routing the lines - mine is not routed how it was stock, I don't think.

[Hey_You]

I would take pictures, but I don't have mine run yet. And my engine is out of the car. I also won't be putting some of them back on (ICV delete)

[JasonBates]

Well, I didn't get it running, so I think I'm just going to take a few pictures of my bay and have you guys point it all out to me.

[Hey_You]

While you are taking pictures, can you take pictures of your alternator and power steering pump adjusters. Those are next to go on for me, and I'm scratching my head on how they are oriented.
