That is very likely the O2 sensor input wire, which is coax and a
very bright green compared to the other wiring.  If it has a female
space connector buried in a rubber boot, that improves the odds.  If
there's a double-male adapter plugged into it it's a sure thing.  If
it's not shorted to ground, you should see ~0.4 volts on it with
ignition on, sensor unplugged.  If it *is* shorted to ground then the
engine will run rotten.  Usual place for a short is where the coax
braid ends, just before the female connector.

YOurs,
