using 05\\' CV running gear in my hotrod

So the hard part is done .....or so I thought. I went and striped out a 05 CV engine trans axles you name it. All went well and was actually easy. when I pulled the entire harness I was very tedious at unplugging all connections and not hacking the harness to pieces, The issue is now that I\\'m sure some plugs will not be used, ABS,AIRBAGS,and such. My question to you all is what is the minimum wiring/things that must be plugged in order for my engine to work, and run correctly. (Engine was left stock so no intake mods or anything figured I get it running first and start from there)(also all smog equipment was left in place except for the gas tank vapor module)
