Yes you do, and that brings up other stuff!
If you get a drive-by-wire engine make sure you get the gas pedal and related wiring. Also you will need to send the ECM off for "Pass-Lock" and rear O2 delete reguardless of what year model it is or own or know of someone who owns EFI-Live to edit the ECM.

Keep in mind that you will have to change the gas tank and fuel pump system as well.

With a good solid donner truck your upfront costs are a little high but selling unneed parts could make this a free upgrade. And this will undoubtedly be the best upgrade you could ever make to your truck (sans: power disc brakes{safety}).
