Assuming that you have the later Bentley, look at page 97.107, the idle
stabilizer section of the wiring diagram for 1987. An unused white/green
wire is shown between current track 41 & 42. It comes from the idle
control unit (ICU) and ends at empty connector T1k. Page 97.103 lists
the position of connector T1k as "single, in engine compartment, left".

Next look at page 97.141, Air conditioning 1986-1988 wiring.
Near the bottom, in current track 16, there is a single wire branched
off from the A/C compressor clutch control wire. This wire ends at the
label "to idle stab. control". The color of this wire is given as
red/blue.

These 2 wires connect in A/C models but the white/green wire just
dangles alone and forgotten if A/C is not present. I just verified this
on my wife's 87 with A/C. Red/blue from the A/C wiring connects to a
white/green of the fuel injection harness.

This leads to a point I have made often. As good and comprehensive as
the Vanagon Bentley wiring diagrams are, there are still errors and
ommissions. I have run across many cases where the wiring colors and
connector pin numbering is wrong. Fortuanately most of these occur
outside of the main wiring section. The A/C wiring, rear washer/wiper
wiring, Camper wiring, Aux battery, etc. all of these have errors and
ommissions. In the above example the wire is labeled as white/green up
to the connector on the main diagram but mislabeled as red/blue on both
sides of the connector in the A/C diagram. In addition the connection is
labeled T1K on the main diagram and T1A on the A/C section.
