[Vwdiesel] ID on inj pump?

[Shawn Wright]

Today I finally received a used inj. pump I got off Ebay. I bought it because 
it appeared to be a 1.9 AAZ style pump modified with Vanagon throttle 
brackets, and had what I thought was electric cold start advance. (a 2nd 
electrical connection with a solenoid and a metal line leading from it. Now I 
see the pump has the mechanical cold start advance, so I'm wondering if I 
am wrong in my assumption about this 2nd solenoid. It appears that it may 
be a secondary fuel cutoff for the delivery pump perhaps?

The pump part # is 068 130 110N.

Can someone shed a bit of light on this please? Thanks!
