E21 Coolant bypass setup?

I grabbed the tube that runs along the intake side of the block so that I could bypass the heater for the intake manifold when I got to sidedrafts, but forgot to get all the attaching parts (more like I couldn't even see what I was doing under that intake manifold!). Does anybody have a diagram of how it works? I know I need to get a small length of hose to step down from the water pump to the pipe, and that the other end of the pipe goes to the heater core, but it's a vertical length and I don't know what to use to bring it back to the heater.

You can just bend the existing heater line down to meet the new pipe you're putting in.

From Zenon's site:

Now that's what I call rustproofing! Thanks, I'd forgotten about Zenon's site - lots of good info there.
