Needed: LTD Bass Wiring Diagram F-254

Hi,
Although I am a guitar player(I started on bass!) I do repair for a local music store. I have been given an LTD F-254 bass to repair. The bass has some type of active tone circuit from the factory (I think) and someone has previously tried to "work on it". You know, cheap green electrical tape on everything, globs of solder on connections, and in my case 5 unattached wires that go to the battery and the input jack (that was glued to the jack plate!). Can anyone supply me with a wiring diagram, drawing, or photo of the cavity on one of these jewels? I have searched the internet for 2 days and written emails to ESP/LTD with the request but have received no response. Any help would be GREATLY appreciated!

Thanks!
