im not sure best i can do is  a photo of the one in your guitar. go to parts express   type in rj45 go to page 9.  what id do is remove the 4 screws  and pull out the plug holder and look for a matching number on the back ot sides. ive included a photo. probably a number on the pcb board   i opened mine and the numbers on the board are as follows   mg1 rj45 revb   pn 35 00 0160   5004   id remove the plug from its mount to see if there are more numbers   on the plug sides.  these dont match neutric numbers.

                                       they have an email  contact on there site and theres  also phone numbers on there web page.  parts express  phone numbers are 937-743-3000  ext 131  or 800-338-0531 ext 131

             if you get the correct part number  please post it for others    thanks
