[Vwdiesel] injector pump shutoff solenoid wiring

[Kneale Brownson]

I've determined the wiring to the shutoff solenoid on the injection pump of my '94 Jetta TD is not working.  I can start the car using a jumper from the battery.
   
  Anyone know where the solenoid gets its power from?  I know the ignition switch is supposed to supply 12 volts to the solenoid, but through what pathway?  
   
  Can I safely run the car with the solenoid jumpered directly to the battery?
