Need Wiring Instructions for Carvin Active/Passive Module

Carvin, strangely enough, does not have a wiring diagram for its active/passive module on its website. This is strange considering all the other instructions/diagrams they have, but nonetheless, it is true.

I am trying to get in touch w/ Carvin, but in the meantime, do any of you have an idea where else I might be able to find such a wiring diagram/instruction sheet?

Thanks in advance.
