2007 trailblazer conversion to a 58

[wutnxt]

I have always done old school drop in's but this time around with the help of some friends this is where I am...I wanted to find a LS engine and after I looked everywhere I found a 2007 LS 2 in a trailblazer AWD with 17,ooo KM on it at the wreckers.

The wreckers said they will give me everything I need to drop into swap it out including a 4 speed automatic because I don't want the AWD portion. So my questions are......

Hows that going to work with the computer and wiring harness ? I am getting the harness complete out of the trailblazer but it's not going to be set up for fo a automatic 4 speed soooooooo how is all of that going to work ?....

Does anyone know what kind of gas pedal I will need or that too ? Will i have to get the trailblazer pedal ?

any information would be great....I have buddy who said he could wire all of it and is looking for information but any info is apprecated...

Thanks
