Sorry, hard to explain via text - i try these pics. I don´t know how a choke is operated by vacuum, so no help here. In the pictures you see:
1. to brake booster
2. PCV valve, you need a grommet for the valve. The valve itself goes in, used to be a hose to the valve on the oe...can´t remember anymore right now, anyway - here it is now.
3. No idea myself, just wondered a few minutes ago what to hook up there.... anybody else?
