The two different units are different idle speeds. The green one is
virtually worthless as it does not correct the idle speed until it drops
to about 700 rpm. The black unit starts to work at ~800 rpm. The were
used in different years. The accessory load has nothing to do with which
unit the van was equipped with.

Subject: Digijet Idle Stabilizer--Green or Black?

I have an '85 Westy.  I  replaced the idle stabilzer as part of some
trouble shooting I did a year or so ago.  I noticed the new one was a
different color than the old one, but didn't think much about it at the
time.  Now I hear there are two different idle speed versions, green and
black?  I assume the Digijets with A/C, P/S and more accesories? got the
higher speed unit, which is black?    I will put my old one back on some
time when I get a chance.  (It was not the problem I was trying to fix.)
Before I do this,  can anyone shed some light on this?

Jay
