Can anyone help me identify the small gauge yellow wire that appears to
emerge from and return to a large bundle right above the  thermostat
housing against the fire wall? My 87 westy has a stock yellow wire
connecter at this point. Mine has a few cracks , and I plan to replace
the worn portion.

TIA.

Philip, if I'm not mistaken, that connector is the disconnect for the idle
stabilizer valve.  It is used during engine setup and tuning to disable the
ISV.  It's also handy when you're having ISV fast idle problems and you just
can't take it anymore.
