Manson Bass electronics - help needed!

Hi all. I'm new here and wondered if anyone can help me get my old 70's Manson bass up and running.

This bass came to me with it's 18v active system in working order. In time, a wire came adrift and I sent it so be repaired. Big mistake! The guy sent it back with the active stuff disabled and a buzzy, weak sound. I asked him to fix it properly and he just wouldn't return my calls.

Anyway, I stripped the electrics out to get the bass re-finished and 15 years later they still needs putting back in...

What I really need is a wiring diagram but as it's got custom electonics, pictures of where the wires go or any other help would be appreciated. I've seen 3 or 4 of these basses over the last 18 years so I know there are a few around, maybe someone here has one the same.

The electrics consist of:

DiMarzio P style split pickup

3 pots - 1 volume, 1 treble, 1 bass

3 active switches - 1 volume, 1 treble, 1 bass

Manson custom curcuit board

Any help, direction, comment will be most welcome as I have fallen in love with this bass again and need to hear it loud again.


Cheers
