BCD cable wiring

I have a BCD cable which I would like to use with a band decoder for antenna switching. The wiring diagram for the cable looks like this:

The Flex USB Cable Interface Guide specifies this output pattern for band data:

Which wire on the cable corresponds to which bit? I am tempted to assume that Bit 0 will be on wire 1, Bit 1 on wire 2 etc. But I have been known to be wrong before . . . . .

    Hi Tim,

    From page 3 of the USB Cables Interface Guide for the Flex-6000 document:

    So you would use Orange (bit 0) through Grey (bit 4). Be careful, the Red wires carries 5 V, so be sure not to short it to ground or any other pin. If you are hooking this up to a band decoder that expects to be powered by the cable, make sure it needs 5 V and not 3.3 V.

    I found the wire number to Bit as you describe.
