The cargo light is turned on by turning the headlight switch all the way till the dome light comes on. By having it work with the dome light, you will not forget to turn it off. 
Actually, a real simple way to do it is let the truck age. After awhile, the resistor or diode or whatever that keeps the cargo light from coming on with the dome light fails, and the cargo light starts to come on when you open the door, just like the dome. And of course, once you close the door, it goes off.
Cool, didn't realize it would still work if the diode failed. Didn't want to take the head liner out to fix. It was a tight fit to get the replacement one in with the bench in the truck. At the wreckers I had no problem since the truck was stripped inside.![]()
