Hi,
I found the schematics for the 2.4L. It was listed under "Z24". I attached the powertrain management schematics below.
As far as what to remove, that is a loaded question. LOL, If it was me, I wouldn't touch anything from the PCM even though it controls things such as cruise control. You don't need CC to start or drive the vehicle, but it could lead to crazy issues with the transmission.
The best I can suggest is this. Look through the schematic and the different things indicated for the PCM. Let me know if you have a specific question, and I'll let you know if it's possible.
Now you indicated wires. Things such as the horn, windshield washer pump, and wiper motor wiring, if you plan to race it, I don't see a need for such things, but again, I'm not sure of your plans.
Let me know if this helps or if you have other questions.
Take care,
Joe
