Diesel Bombers - diesel swap

Hello, I am a new member,retired from my business and am working on my toys,always. my current Dodge 2001 3/4 ton 4x4 diesel is my fifth and is just a plan std. unit as all the others have been. I noticed this website one evening and became interested because I am in the process of switching the entire drivetrain from a 2006 Dodge diesel dually 4x4(rollover write off) into my 1996 Dodge 3/4 ton 4x4 that has a v10 and I am hoping to get some input about adapting the 2006 underhood wiring to the 1996 underdash wiring so everything will work, as I want this unit to pull my other toys to some shows.
