Sounds like the wire/connector used for the AC compressor signal that
tells the idle controller when the AC is on so it can speed up the idle.
The wire sits there unused unless the vehicle has AC. Connector T1k on
Bentley page 97.107 crrent track 41/42. The AC pages have the wire color
and connector number wrong, page 97.141 current track 16.
