I acquired a wrecked 2003 Trailblazer EXT a few months ago and am in the process of pulling the LM4 drivetrain and a couple of other items. I'll then sell the carcass to the salvage yard.
I haven't decided which vehicle I am going to drop it in, but I figure I'll probably use ECM/PCM, engine, transmission, and tbi. The timeline for rebuilding/installing the LM4 will probably be over the next 5 years as I get various things done.
The questions I have are:
1) what exactly to pull out, and
2) why to pull things a certain way
For example, every video I've found they remove the wiring harness, even thought they state that they will be re-using it. Why? If I plan to use the wiring harness wouldn't it just be easier to leave it attached to the engine and unmount cables from the body? are there certain parts of the underhood fuse box or the wiring harness I won't be using?
I've looked for other YouTube videos but haven't really found anything that answers these questions.
