No, the contents of any given bag do not correlate to any particular task you may be working on. The bags are used by Van's to group smaller parts in "easy" to manage inventory lists. In your kit documentation, you should have a multi page listing of bag numbers, and under each bag number you will find the part numbers and quantities of each item listed for that bag number. You will not have all the bag numbers that are listed. That particular listing is for all numbered bags that Van provides for the entire fleet of his aircraft.
Also, your documentation list BOM ( Bill of Materials) will list which bag numbers are included with your particular kit.
So, if you are so inclined, determin which bags are included with your kit, then inventory each bag against the listing for the bag contents.
