[Vocabulary] to go out of sequence

[Iryn_]

Hello, everybody!

- So you can't put the interior in without this cable. And so we can either make a whole bunch of cars - minus the interior – which means that you got to stick them up in the yard.
- The resale value would be no good.
- It can be done, but... the *** things go out of sequence.

Could you, please, tell me what is the meaning of the phrase in red, and what does he mean by "things": are those cars or cables that go out sequence?
Thank you!

It means that the assembly of the cars goes out of sequence. Usually cars are produced on an assembly line, each part of the car is assembled in a set sequence. If one part of the assembly line is not functioning, the cars will have to go back to that stage later.
