Not seeing others jump on this, and I don't know too much about differences between 12 and 14. I would start with seeing if the ports in the 13 jump seat were available in any version of the 12. If so, you might have the plug hidden somewhere under your current seats. If you have access to a 12 or 13 with the jump seat you bought, look to see where it is plugged in. Could always go test drive one on a lot to get a chance to take pictures of it. Good luck.
