testing switchover valves for 300D/123

Quick question,

On w123/300D's the switchover valve on the firewall is plugged/blanked off at the top vacuum valve (which is normal on most w123s).

The other two openings go to the banjo bolt and ALDA. According to search results, people say you can blow through it with the valve unplugged.

But what about when it is plugged? One of the leads gets juice. Should I be able to blow through the valve when its plugged in?
