Coil Pack Part Number Location

[fataugie]

I'm going to replace my wires on a 2005HD 6.0L GMC. They list two different wire kits, depending on which coil pack is installed. Problem is, I can't find the number listed on the pack. Does anyone know how to tell which pack I have installed?

 

Thanks

Nevermind, the dealer looked up the VIN and matched the wires based on that.
