Need iBook G4 trackpad wiring schematic

[The Nightflyer]

Here’s the deal: I’m trying to build a Hackintosh/Mac Mod/whatever. It’s going into the empty case for a Mac SE. Originally, I took the logic board from an iBook G4 with a bad display, installed that in the case, and installed the trackpad module in the top of the SE – it’s pretty cool. Unfortunately, the board failed - probably something to do with the big gynormous crack running through it severing several traces - so I need to do something else. But I still want to use the trackpad, which as I said is now part of the case. So here’s the thing. When it was the G4 logic board, I could wire the trackpad direct to the board, using the connectors that came with it. Obviously that’s not an option, so I’m going to need to splice it to a USB cable. But I don’t know which wire goes where or does what. that’s why I need some sort of schematic or diagram indicating what each wire corresponds to in a USB cable - so I can connect them. Obviously, this plan is all blown if there is no such way to do that, or if there are different requirements- power, etc - between A USB cable and the trackpad wiring. But one thing at a time. So there it is. Does anyone by chance have or know where to find that info? thank

I do not have the schematic. However, I'm pretty sure the track pad is ADB based, not USB.

Just checking my iBooks, it looks like the last gen which has the Radeon Mobility 9550 GPU uses USB for the Keyboard and Trackpad, but earlier models used ADB.

Well, that narrows it down. I just had a look at the Apple Desktop Bus page in Wikipedia; it has a diagram of the ADB plug, identifies the wires, etc.

So, next question would be, which wire in the trackpad corresponds to which wire in the ADB? I figure I'll need to connect them to an actual ABD connector, and from there to an ADB/USB adapter.

So, any ideas on which wire is which? BTW, my electronic testing resources are one inexpensive multimeter I bought at Radio Shack back when there was such a thing, and that's it.

Thanks
