replace mother board WR49X10152

Hi, I just replaced the mother board in my 5-year-old GE refrigerator model PSC25SGSCSS, using the WR49X10152 kit. I basically copied all the original connections on the old board to the new board, the refrigerator appears to be fine now. But, the questions are what to do with the j14 on the new board which is not on the old board (do I need to plug anything onto it?), and what to do with the extra cable coming with the kit (am I supposed to replace any older one with this?). The installation guide coming with the kit is not clear, I guess it’s generic. Thanks for the help.

There is no refrigerator J14 plug in your refrigerator, no need to be concerned.
