Views contextual filter I really would need some help with contextual filter.

I have a content type I use for products, different kind of security cabinets. In this particulary case it is aboyt burglary safes. They have a classification of 0,1,2,3,4,5, S1 or S2. So all burglary safes has one of these classes. To give them the class I have created a Vocabulary with the name "Burglary Classes" and there I have created the classes 0,1,2,3,4,5, S1 or S2 as terms.

In Views I have made a block with a table presenting all burglary safes, containg fields like dimensons and weight and so on and have brought in this table block to the Content type, as a field, and it works just fine.

Now to my question; 
All products in the Content type are not burglary safes so some are not classified according to 0,1,2,3,4,5, S1 or S2 , but I can't firgure out how to configure the Contextual filter.

I want ALL safes classifed to ANY of the terms 0,1,2,3,4,5, S1 or S2 to appear in ALL of the nodes having ANY of the terms 0,1,2,3,4,5, S1 or S2 but NOT to appear in any other node

The best shot I have had is filtering so that in the node only products belonging to the same Burglary Class as the node itself, appears. But as said, I want all products with a burglary class to appear.

Greatful for your help

(On request I have tagged the question for Drupal 7! Sorry for forgetting)
Have you looked at the PHP filter module? I believe you could make two views, one which displays the burglary safe items and one which displays the non-burglary safes. Add both blocks to all pages, then use the filter module with a PHP expression to decide which to make visible and which invisible.
