Polestar 2 boot fire

[Marky mark]

So i'm after some guidance.
I've just purchased a Polestar 2 that's had a small electrical fire in the rear right boot area, as the car has been stripped i'm not sure what I might be missing as the car has had items removed since the auction pictures. The first items that are missing are the powered tailgate rams so I'm what else has been stolen or removed from it. The car arrived with the burn't section of loom  also cut out so again I'm strugging to determine what other items could be missing, I do still have the amp, do they come with sub as standard or is that an option? The missing section of loom looks like it would have returned up the C pillar where it would have supplied the tailgate wiring and picked up the seatbelt tensioner, am I missing anything else.
If it makes a difference the car seem to be a 2024 model as its 2wd with the motor in the rear.
Are the looms standard between all model on the Polestar as I've noticed that the left loom seems to have spare plugs for other accessories wrapped in foam.
Any guidance would be greatly appreciated as I'm struggling for information as as its fairly new and I found the dealers very unhelpful here in the UK.
And for anyone thats wondering the car still drives, there was no one more surprised than me

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.
