MK1 MX5/Eunos headrest speaker wiring connector

Hi there, I’m after the wiring connector (left/right) that sits under the seats and connects the headrest speakers to the head unit. I only really need the headrest speaker side but if someone breaking a car and can supply both left and right connectors complete then that would be great. Im looking to uprate the the stereo system but would like to be able to return to standard so would rather not cut the wiring.
Thanks Andy
