Default How to connect Hypex Molex to XLR?

Hi
I already have finished my first Hypexamp (400UCD SMPS 12000, Softstart) and now i have to connect the Hypex-Molex to RCA and XLR. The Molexwires have 1 red, 1 white wire and little separate black wire (see pictures below). I already have soldered the connection between RCA and XLR (is this correct?). So now, how i have to connect the Molexwires with the XLR? I would be very pleased to get some help!
Thanks a lot

Q: I would like to switch from XLR to RCA and vice versa without the need of pulling the unused cable out of the amp.
A: That basically amounts to a source selector. Refer to http://www.hypex.nl/docs/wiring.pdf for information of how to wire an RCA connector to the UcD module. Install a DPDT switch to connect the hot/cold inputs of the UcD module to either pins 2/3 of the XLR connector or to the signal and shell contacts of the RCA connector. Note that pin 1 of the XLR connector is not switched, but remains hardwired to chassis. The RCA shell contact also remains hardwired to the chassis. This means that when the DPDT switch is set to RCA, the cold input of the UcD module is grounded via the RCA connector.
