Which years did Spiders have a light with a switch on the underside of the rearview mirror? I have a plug that goes to nothing above my right speaker in the footwell. I'm thinking that it went to a lighted mirror in previous years. There is also a plug under the left side of the glove box that is the same type of plug and I believe that it is for the map light option. Both of these plugs have two wires and reads 12v with one wire being hot, the other ground. Don't ask me what color they are as my car is in the garage and under a cover currently and I am too warm right now to go out into the freezing garage.
