TopGun MD-1 modulator / EPTDX2912Z board

I'd like to install a TopGun MD-1 on my Connex CX33HPC-1 radio.

I can't find a lot of information on the EPTDX2912Z board though. It seems even finding a legible schematic for the board is a little difficult. Why does it always seem like it's me that ends up with some off the wall something that there's little support for? LOL

I've been told however that this is basically the same board as in the Galaxy DX979 and 66V2. I can't seem to confirm that though. The TopGunTech website gives instructions to install the MD-1 in a Galaxy DX979, but I'm not so sure it will work with my Connex. Anyone have any additional information they can offer up to assist me?

Thanks!
