Yeti 2012 Where is the parking speaker?

I've suddenly got this fault code (Parking speaker short or open circuit) unrelated to other work and was o.k at the last scan. Since then the spare tyre and tools have been in and out the boot. I've read conflicting info - Behind nearside B pillar, underneath rear headlining. Both need work to inspect and I'd appreciate a location heads up if anybody has replaced theirs, seen where it is, or know if wiring/connectors run in the tyre well? I should also know where the park assist module is to check its connector.

Thanks
