Is the Diesel Pump "fuse-box-fed"?

[vanagonvanagon]

Hi, all..in an attempt to fit a "stealth" cut-off switch on my 1.7D van, I am hoping someone may be able to point me in the right direction as to whether there is an ignition live wire somewhere on the fuse box which "feeds" the solenoid on the diesel injection pump..the one that comes on and off with the ignition and cuts the fuel supply when off...I want to put a switch across that wire in order to manually cut the power as a form of immobiliser...so rather than running a wire back to the front of the van from the pump itself, I was wondering whether there is shorter route I can take up front?
Many thanks.

black wires are ign+

specifically for the pump solenoid, or just generally?

The switched 12v is the black wire the is in the rectangular 3 pin connector that sits in the black junction box.

generally. DIN standard AFAIK (or VW standard)
