Where is the ignition coil located on a 2004 Chevy Suburban LS?

The 2004 GM V8 Engines Use a form of Coil-On-Cylinder Ignition. In effect, The Engine in your suburban (4.8l, 5.3l, 6.0l, or 8.1l ) acctualy has eight (8) ignition coils... they are located on the valve cover mounted rail (4 per side) at the top end of the spark plug wires.

I have 2004 Chevy classic car not surburban.
