I know this post is old but I figured I would post up for any body else that used this topic.
Today I went to a local pick a part and to my surprise I found an 86 4Runner with one in it and I grabbed it. it has 4 bolts that hold it to the dash and a 1" hole for the wires. If you were to install one im sure you could put it in any dash. just 4 small holes for the mounting bolts and 1 larger hole for the wires. There were only 2 wires and im sure they are just for the lighting. they were black and black with a white stripe. the wires come up from down by the radio wires and if you cant find them you could just run a positive and negative wire for the lights.
