The ECU one looks like this if you can see?
Coming from the bulkhead and going under the main wiring loom to the inlet manifold brake servo/vacuum feed.
And if you can see this pic this is where the 1st part you asked about goes.
The top of the saucer goes to the throttle body, the bottom connects to the t-piece line coming from the breather pipe and the one on the side of it goes the the s shape pipe that goes from the ISV to the back on the inlet manifold.
Hope this helps.
