Perhaps i should have been more clear. The list of things i have are either already done, or we are in the process of doing. So i dont need help with that

I need help with the wiring harness from the chevy truck. I plan on using NOTHING from the inside of the truck. I basically need to know what i need from the giant pile of wires in the engine compartment to get the motor running right once we try to start it up??? I have no plans to buy an aftermarket wiring setup, i just want to know if i need every sensor, or plug, or wire in that loom??
