Courtesy /glove box lights

[Steve Cole]

My truck was a bare bones, no options truck. I have picked up a glove box light and two courtesy lights that I would like to install. As you know, My 1968 original fuse box has very limited connection points. My dome light is controlled by the light switch knob, (no door switches). So my questions are: how are the lights wired? The courtesy lights I would like to control with the headlight switch, same as the dome light. The glove box light should be hot all the time as well. So how do I wire these lights? (Fuse box/ switch connections and splicing wires) Also, where would the courtesy lights be physically mounted? I found two holes on the underside of my dash area but the are on the far ends, seems like the lights should be closer to the middle.

Thanks for the help!
