I have a 2005 cavalier circle track car I'm pulling the engine to do a swap because I blew the one up that I have in it, I have a donor car a 2004 cavalier, both 5 speed Manual with the Eco this is my first time doing this so I'm labeling and marking everyone and there's a ton of stuff

I'm looking to remove as much factory electrical As I can without having an issue does anyone have insight into what I could remove?

You need all the sensors. We run a 02 Cavi. I gutted all the wiring out and made my own engine harness. All the dash wiring, BCM rear end wiring everything.
