Lg8 3100 replaced by l82 3100 wiring help

[dahl87banshee]

I swapped my the motor from a 98 Buick century into an 03 buick century, it's all bolted in but a few plugs are different on the wire harnesses. What changed in these years? Can I get color codes for the wires and splice them? If I have to change more between the cars what all should I change? Need help asap

only obvious thing coming to mind is the fuel injection system. The 1998 setup would have the fat injectors, while the 2003 would have the skinny ones. You might want to make sure that the fuel rail is the same.
