mobo diagrams?

Is there a good place to go to find diagrams of where things are on a ps2 motherboard and components? I know my way around an xbox, but not the ps2 yet.

I have a ps2 (not sure which version since the case had no stickers) that uses mostly wires instead of the ribbon cables to connect the dvd drive to the motherboard, but there is one wire connector to the rear of the drive (next to the copper colored ribbon connector) that I have no idear where it goes. It's two black wires with green connector ends. The end is connected to the motherboard, but I dunno where the other end goes! :crazy: I don't see any other green connectors nearby either! Unit boots, but the drive won't slide out (I hope this is the issue for the drive not sliding out though)

any advice here? :-pray:
TIA!
thx
