93 T/C wiring harness

I changed the alternator on my Town Car, but I can't remember where this red wire with small plug goes.
The harness goes to the intake manifold but then this little red wire...
It would seem to plug into the side of the alternator but there is no screw for the plug to go.

Looks like there's no 1993 guys here??

Try over at LOL (http://www.lincolnsonline.com/cgi-bin/ultimatebb.cgi?ubb=forum&f=3) there's quite a few early 90's guys there.
