5.7 Hemi stock wiring harness mods

Hello I've purchased a 5.7 hemi from a Canadian 2005 dodge pickup I plan to swap into my 1972 Plymouth scamp with a 318/727.
I've researched the majority of the mods and parts I will need but I am having trouble finding information on wiring. I've heard Canadian vehicles wiring harness is different on the body side of the c130 to the fuse box.
I'm looking for information on what I need to use and what I can eliminate from the harness and the motor., Wiring diagrams, anything that might help with wiring up this swap.
Thanks for your help! I'll make sure to create a build thread as I work on this swap.
