Customer Question

I just purchased a JW BP-SY1 External Battery Pack from Amazon for my Pentax AF540FGZ Flash. The unit is compatible with various flashes; only requires the appropriate connector cable. Incredibly, Amazon does not carry the connector for Pentax ((BP-PK1). Any ideas where I could locate the right connector cable?
JA: What's the make/model of your camera? How old is it?
Customer: Pentax K-5, approx. six years old.
JA: What happened right before this popped up? What troubleshooting have you tried?
Customer: Sounds like I am not talking to a real person.
JA: Anything else you want the camera expert to know before I connect you?
Customer: No.
