Hi John,

The Ault SW-305 had inconsistent colors, batch to batch. I could send you the colors for two versions I have here, but it would be best for you to ignore color and trust your ohm/voltmeter. The TBolt only needs 4 wires (+12,gnd,+5,-12). See also:

If you have more questions let me know, off-line (I was the one who created all the TAPR TBolt kits).
