It will work if you swap the connectors for the fuel injectors.

I used the 5.3 harness with no modification for my swap into my Jimmy, using the fuse box out of a 2000 Silverado to make all my connections. It would be possible to modify the harness, but you will need to add a few relays and your own fuse panel to do it properly.
