you can use it, you'll have to change the injector plugs, and use the truck pcm. Or swap a few pins around and can use a car pcm.

Yes. Without swapping any pins around....

The truck harness is what I used on my last project with a truck ECM that had been flashed with an F-body operating system. No real changes need to be made other than cosmetics and injector plugs as others have said.

That and the truck harness leaves your ECM on the drivers side strut tower area unless you unwrap it all and extend.
