Making a V20/20 from an M9000

[BiggerHammer]

I'm working on converting an old M9000 that was missing the top box into a Gamemaker HD. I threw a cheap 20" LCD up top, installed a 1G MPU with dual video card and installed the GMHD button deck. My problem is that the motherboard on this machine does not have the two 10 pin white molex "Spare Power" connectors on the lower right hand side of the backplane board like my other GMHD's. This is a problem because there is no place to connect the power for the GMHD button deck controller. There is a black connector marked "Aux Power" on the backplane. The harness that's currently plugged into it runs up to where the top box used to be and has a 10 pin white molex on the top box end but I don't know if it's safe to connect my button deck controller to it. Has anyone run into this in the past?

I too am wondering about this for a Bezel/Lighting Controller card. The backplanes on M9000s are so limited compared to the newer V20/20 and S9000s.
