You can do what you want but, why cut your cars wires when for about $ 8-10 you can buy a connector to plug in then you have color coded wires. You can buy them at walmart or probably any similar store. Here is a link to them from one source. Sorry I dont have the wiring diagram your asking for but thought Id suggest a better method. https://www.scosche.com/scosche/connectors/gm.asp

a 2003 monte carlo does not take the standard 32 pin, it's takes a 70-2003 and you have to run your own acc wire
