How do I install female XLR's in Aragon amps?


Long ago I bought two Aragon 8000-series amplifiers with RCA inputs but with blank ports (plates with screws) to allow installation of balanced XLR jacks (female, I presume). I just bought a Krell processor with balanced XLR output, but unfortunately, Aragon has gone out of business and I can no longer find a dealer to convert the amps to XLR. I would rather do it myself by purchasing Neutrik jacks and soldering the wires.

The problem is that I do not know which wires on the RCA jacks to solder to the XLR's. I assume that the outer-shell RCA wire (ground or female) is to be attached to the ground lead of the XLR and the center RCA wire (signal or male) is to be attached to the positive lead of the XLR. Is this right? But where do I attach the third XLR lead in the amplifier? Is there a shield wire? To the chassis?

Aside from the wiring problem, will I have a problem with a larger input voltage or any other unforeseen problem. If Aragon provides the port, I assume not, but I'm not sure. Please help!
