I am wondering where ignition coil E is located on a 2002 Chevrolet Silverado 1500

I have never heard the letter designation for ignition coils on your 2002 Chevrolet Silverado. To the best of my knowledge the coils are numbered to the corresponding cylinder, 1-8. If you can tell me where you got the letter designation perhaps I can help you.
Coil E is the reading that i got on a code reader. I have since found out that coil E is actually the coil for the # 5 cylinder, which i replaced and the truck is working fine.
