hi guys, I just bought a 2004 6.0 out of a Silverado and it did not come with a wire harness or PCM. What wire harness and PCM will work with this? What I mean is, what kind of vehicles would work with this? Even if I have to change the DBW since I'm starting from scratch. I know different years and vechicles will work but not sure which. And I don't want to have to change the connector plugs if possible. Any help would be great. Thanks

Have you looked on LT1swap.com? Lots of info there, not sure if it will answer your question though.

If you are going to stick with drive by wire, you can use any green/blue pcm drive by wire harness (mostly 2003 - 2007 Gen III Truck engines), car applications will work as well however, injector connectors, maf connector and location of map connection vary. TAC Module and Pedal wiring are also different.

If you are going drive by cable, I would recommend going to the RED/BLUE 411 PCM. Yes, there were some vans and 2004 GTO green/blue applications that ran drive by cable, but you are better off going to the red/blue configuration as they will be easier to find. We have all these harness applications in stock if you decide you want to go with a new standalone harness. Give us a shout or pm.

It can be any GenIII engine harness (4.8, 5.3, 6.0). Be careful of flex fuel as the injector connectors will be different.
