not sure but some lighter sockets are lit around the border, that wire could be for that. does the lighter work? also, if i remember right.... there is a large press shaped nut that is a little bigger than the dia of the lighter case that holds it all together. you have to reach around behind and sort of undo it with your finger tips.... or was that another car i worked on... sorry, not sure. if you had the time i would say goto wallmart and look at the replacement ones in the clear wraping. but there is a hot wire coming off the center rear of the lighter, female end on wire plugs over the male end on the lighter. hope that helps ya a little.
my other 2c is, dont try to take off the center console moulding if you dont have to, it is a mojor pain! and easy to break. good luck! :-/
