No. Guys it's easy. Think of it this way. If you have a switch and it has a light in it. It has to have a + and a - wire ran to it. So most of the time your switch will have 3 terminals if it is a lighted switch....
One terminal from the battery or fuse block supplying the switch power. Then one terminal going to whatever device your switching on and off..
When you flip the switch you complete the citcuit...
How would this make the switch illuminate? It couldn't. ...
The switch has no ground... so what you would do is wire whatever terminal on the switch that is marked as a ground connection (usually a bunch of progressively smaller lines to a point ) to a point on the chassis of the SS or if you have a ground wire handy you can connect it to that.
And there ya go. You have a lighted switch.
