    I found this look Single wire, Green/Red after doing first maintenance of

    a 1990 with a B280F .    Car doesn’t seem to have a problem missing this

    cable.   Maybe a possible test point.   Green-Red on my 1989 wiring book

    point to temperature sensor.    Green Red

    As I recall, the temp sensing wires are all part of the wiring harness and not run as a single wire, at least it so on my ’87. I can take a look at mine again, as I have the engine removed, where this wire might lead.

    I figured it out.  It is the +12V for the engine compartment light.
