[Elecraft] 15 pin cable question?

I received some cables with a recent K3 purchase that I have a question about. They appear to be part of a cable package listed on the Elecraft site, but I'm not 100% certain. What I have consists of a Male/Female 6 ft. 15 pin cable, a Y 15 pin cable, a Y rca cable and the TX interrupt 15 pin

That is the right cable. You can use it between the K3 and KPA, the KPA and KAT or the KAT and K3. Remember, the correct cable configuration for using all three together is the AUX cable from the K3 to the KAT500, then another from the KAT500 to the KPA500. Enjoy your K-Line! - Jack Brindle,
