Does anyone know where to get Carvin active/passive wiring instructions?

I just purchased Carvin's J99 pickups and the 505SP 18v active/passive piezo bass module used in their P Series Basses. To my surprise there were no schematics or wiring diagrams to be found. I am currently trying to get in touch with tech support at their home office. In the mean time does anyone have any experience with this particular module and know how to wire it?
 
I just got one of their preamps today (non piezo 18V) to replace the original in my Icon 6 and it also doesn't have instructions or schematic. Luckily I can just copy how the original is wired, but it is surprising that there is no documentation at all. If I was installing this in a bass that didn't already have one I would have no idea where each pickup wire goes, because the circuit board isn't labeled either.

Did you ever hear from Carvin?
