It's safe for you, only 12v battery voltage, but you need to prevent shorts. Disconnect the battery or remove the fuse, cut that burned connector off, then separate the wires and wrap each end separately in a few turns of electrical tape. You might also want to tape them to something so they can't disappear and be hard to retrieve.
Finding a new connector may be a lot harder than finding a USM module that has just been chopped off by the breaker and still has a bit of wire with connector attached.

(As far as I know, all USM modules from any 147 are interchangeable. Same design and connections, different colours, but it's easy to re-use your existing housing)
That wire can then be spliced to your wires. This should be done using soldering and heatshrink, but Wago connectors, chocolate strip, are also available. Don't just twist and tape the wires together, if they separate they could short.
Glad you mentioned having changed the door switch. That explains the need for proxy alignment. I was just a bit concerned it might indicate some deeper problem with the body computer behind these issues. Seems it isn't
