Anyone have a diagram of the routing of the spark plug wires on the 5.7? Seems to me its impossible to hook them up wrong given the coil pack design but I want to be certain. Thanks.

 

What year is your truck? Mine doesn't have any spark plug wires to worry about, but I know the design was different in the earlier year Hemi's.

 

2003, that's awesome about the new ones. Mine has coil packs, and each coil pack also drives a 2nd plug (hence why it seems impossible to mess this up). However it is a mass of cables and they have weird numbering on the actual cables (2/3, 1/7, etc.).

 

hmm, I know there are a bunch of guys with the 03-05 Hemi's on this board, I am sure someone will be able to help, when I changed my plugs, I never even unplugged the coils, just moved them out of the way and then slapped them back into place.

 

 

What a mess LOL
