[Vwdiesel] injector pump shutoff solenoid wiring

[James Hansen]

Just in case it hasn't been mentioned, I'll do so.
The wire is direct from keyswitch  UNFUSED.  If you short this wire to 
ground, it is bad.
Every last one should have some kind of mechanical restraint (zip tie, 
etc)on the wire to keep vibration from killing the wire where it is 
crimped on, then it falls off, and shorts, and all the smoke escapes 
from the wiring harness from keyswitch to solenoid.
I second the wiring harness connector nomination for the "POS Award" as 
made by Sandy.
