Magnum wiring help

My 5.9 and all associated wiring/pcm came out of a 98 3500 straight drive truck. Getting a subscription to Alldata sounds like a good idea that I may try when I get time to try and work on it. A friend of mine has a garage, and uses Alldata in his business....so I may pay him to print out the wiring for a 98 3500 Dodge truck for me.
