a couple of lighting/bulb questions

alright i have an na 86GLL and the key ring light didnt work so i tested it and got no power, looked for the other end and its an open plug above the steering column. where should this be plugged in to if anything? if its open why did it come with a light there at all when its supposed to have "everything but the turbo stuff"?
Does anyone know what kind of bulb the turn signal lights are? or the cruise control light?(maybe its a 74).

The map lights i read on the digital dash color change thread were ba## but cant find those anywhere, even with sheets showing the different bulbs that replaced other ones.

Then the lights that light up the key ring on the outside of the car.

How do you remove the glove box light? i know what is a 74 but it looks like it twists out but i cant twist it out.

Thanks in advance.
