1993 Chevy Silverado firing dist

Hello, I don't know the litre size of your engine? I don't trust pictures in books. Put the number one cylinder on top dead center of compression stroke, then check which coil tower the rotor is leading into, that tower becomes number one, follow the firing order around the cap. Somebody correct me if I'm wrong, I believe that procedure will work fine on this vehicle. If you change the number one location much, one or two plug wires may not reach, no big deal. Just swap too short wire for longer one.

If you give me the litre size of engine, I'll post picture.
