Let's try again.  Earlier I posted to vanagon.com asking for info on the
various color codes that might be encountered on fuel injectors for a WBX.
I asked because I've ended up with two sets of injectors, one with the
plastic part where the wires attach that is yellow, the other set blue.  And
when I look at online vendors pages I see (assuming the picture is correct)
either blue or green.
Now, it there a difference based on the color? I'm making the assumption
that Bosch would use distinct colors on such a product only to delineate
differences.  In addition, in a recent post (or link provided by someone) a
mention was made referring to the color of the injectors, I believe saying
'gold' was correct.  Try as I might, I can't find that post or reference,
but the reference to color was made causally anyway, no details.
So, can anyone answer the question.  Do the colors mean anything and if so
what?  And which is correct for the Vanagon 2.1L WBX?
