The ls swap has been done so many times that the amount of information it there can solve all the wiring issues. There are aftermarket harness or you can do like I did and go through it one at a time and modify the factory harness from the donor car. It didn't take to long and is an excellent way to get a good grasp on how everything works. The engine is actually very simple as far as the wiring harness goes. It takes some time to figure out all the external connections though. But just one circuit at a time
