Need Help on Ecu Part Number

[Snoopee]

I need help on locating the serial number or the part number for my 6th gen maxima.. The ecu in the car is messed up and it's not the original one..I tried calling the dealer to give me the part number or serial number but they said its against their policy..wtf!?!??

And there's different ecus available based on features or what not and I don't wanna buy the wrong one..

Is there a way to find out or that can get the part number based on my cars VIN??

2004 maxima
VIN - 1N4BA41E24C847216

I appreciate it if anyone can help me out

Thanks
