No....and yes.....if you are talking about Mike's wire........Mike can explain the details.
If you are talking about the Pink C17 wire.....
you do not need to take it for a ride....you can observe the secondary actuators (canister shafts) move as you ground the C17 wire
Without Starting the Engine. Now if you were to take it for a ride you can assume those secondaries are working just like you seen them work by grounding C17 and looking at them as I suggested through the middle Plenum runners.
By grounding C17 and watching the Vacuum Canister shafts move you have proved complete mechanical integrity of the secondaries as well as functional integrity of the Vacuum System including the integrity of the vacuum system secondary Port Throttle Valve Solenoid shown below.
In the photo below you see the Secondary Port Throttle Valve Solenoid, The infamous Check Valve that checks (closes the port to the passenger side of the Plenum when Plenum Vacuum is less than required), and the Secondary Port Vacuum Reservoir.
The little round in line cylinder with white and black ring is the check valve itself.
The Secondary Port Throttle Valve Solenoid is an electrically operated valve with the electrical wire not shown.
