hot engine after-run circuit

[amalventano@sc.rr.com (Allyn)]

when i put the 2.0 in the rieger i was left scratching my head when
reconnecting one of the wires. on the right side of the head there are 4
senders. the 2 bottom ones are easy (color coded plugs), the upper rear is a
tab that sticks out (also easy, since there is only one plastic covered
connector for that as well). the upper front is a flat disc thats meant to
take a typical crimp connector type plug, only sideways. the catch is that
there is another one of these same flat discs at the rear right side of the
head, yet i have only one connector to put on. im fairly certain the wire is
to the after-run circuit, but the bentley gets really sketchy when it talks
about this circuit. i cant find the wire in the schematics, and cant find a
physical head-sensor layout in there either. has anyone figured out what
goes where as far as these single wire connections go?
