Release tailgate on 2025 Custom with button disconnected.

[jayc001]

Help. Whilst fitting a camera for rear dashcam I have managed to close the tailgate with the button/numberplate lights unplugged. There seems no way to release the lock to the tailgate either on the keyfob or dash. I have a bulkhead fitted so no way to get in the rear and manually release.

I have Forscan but can't see a way to control the lock. FYI it's a E-Transit custom if that makes any difference.
