I have a dollarVars term filled with things in this format...

Message 1:  
Header1|Value1|Header2|Value2|Header3|Value3|

Message 2:  
Header2|Value2|Header4|Value4|Header5|Value5|

Message 3:  
Header3|Value3|Header4|Value4|Header5|Value5|

Etc.

My current filter looks like:

filter {  
dissect {  
mapping =\> {  
"message" =\> "%{dateTime},%{id},%{stuff1},%{stuff2},%{stuff3},%{stuff4},%{stuff5},%{dollarVars}"  
}  
}

```
mutate {
convert => {
  "stuff1"=>"integer"
  "stuff2"=>"integer"
            }
       }

 date{ 
  match => ["dateTime", "yyyy/MM/dd HH:mm:ss"]
     }

```

}

What can I do to take my dissected dollarVars and break it up into the header with its respective value (the one to the right of each header)?

I suspect this would use the csv filter somehow using "|" instead of "," and somehow telling it each dollarVar odd column is a header and each even column goes with its respective (n-1) odd column.

Can you give us an example snippet of what's being ingested? I'm not 100% following the examples you made.
