outside temp sensor? do you have this switch? > http://www.germanautoparts.com/Volks.../Climate/276/1
should be a round hole in the passenger lower vent on the lower front bumper that houses this switch.
Sounds like it's for one of the horns. There should be two on the passenger side. The bracket on the lower one tends to rust out if you live in a climate with snow and may have been removed at some point which is why you can't find where to plug it in.
Could also be for the switch mentioned above too, but I think those are more commonly under the rain tray.

well yes, there are 2 horns so if he's got one then that should be it, perhaps he's only got one horn and needs a replacement...
I wasn't aware that the outside temp switch came on GL-gls models, actually I'm pretty sure they didn't but thought I'd offer that as a possibility.
you said you bought a full harness with plugs at the junkyard?
try disconnecting your harness (right behind the hood latch), connect the new one with horns plugged in and see if that works. maybe your harness is bad somewhere.
