Coupe GT - unknown dangling wire

[Marco Weibel]

Hello

Patient: 84 CGT

Doing the final check before she takes us to Florida on Saturday... I saw a single wire hanging under the car just after the front subframe. After jacking her up in my snowy driveway and laying into the sludge to further investigate I saw that that unplugged wire is routed together with another wire from under the battery tray, following the downpipes and going by the gearshift linkage.
One wire goes up towards the end of the tranny and in my case seems to be plugged in. (can't quite get an angle to see up there)
Where would the other wire plug into?(single flat connector with rubber boot)
I can't find any spade terminal close by.
Reverse lights work.
Parking brake light works.
.... what else is down there ?

Regards 
 Marco
