For anyone interested, the car has been repaired by splicing in a section of loom in the rear corner of the car. The loom came from an 2023 model but turned out the earlier model but higher spec. The loom gave me the Harman amp wiring which was a big help as this was on list of upgrades. The main difference was the connector for the rear camera everything else matched up the same, the 360 camera system is different on the later cars.
When fitting the speaker wiring it was notice that there are 3 pairs of wires supplying 4 front speakers on the base audio setup which turned out the drivers ( i'm in the UK) speakers share a common pair to the A post before it splits to the pillar and door connector. So when adding the Harmon setup I had to run another pair from the amp for the door speaker and isolate the other wires. I should say I've replaced all the speakers too and found that while most of the speakers are a straight swap the rear door speakers were missing the wiring in the door loom between mid/bass driver and the connector for the door card, the wiring was present on the door card tho.
