Hi! I recently bought an open box XAV-AX8000 that is missing the wiring harness, and I am not sure that the retailer will be able to find one to send out, so I have been looking for one online just in case. The issue is that the site that Sony links to on their support page (Encompass Parts) does not list this part on their site. Does anyone have a link to this part from a reputable source? Is the harness from the AX5000 compatible? That part is on the parts site. Thanks!
