    you will need the complete wiring harness if you are doing a complete vortec motor, as well as PCM.

    X2, & you're also going to need the fuel pump from the donor truck (60 psi compared to 12 psi), & probably all the fuel lines due to fitment issues, & fp relay. You may also have issues with fp fitment to your tank. Do you have access to the donor vehicle where you can take anything you want, or is it in a salvage yard? This is a nice swap, but it's going to nickle & dime you to death if you don't own the donor vehicle.
