'Which' is both a subordinating conjunction and a relative pronoun. My question is how can we figure out whether it's behaving as a subordinating conjunction or a relative pronoun?
Can a subordinating clause be parallel to a clause?
There is a small difference between subordinating conjunction and a relative pronoun. The function of the subordinate conjunction is to join two ICs. When one of the ICs takes the subordinate conjunction, then that particular clause becomes a DC or subordinate clause. You remove the subordinate conjunction, then both ICs can be seen through clearly
e.g., The doorbell rang when I was about to hit the bed.
Here both the clauses 'The doorbell rang" and "I was about to hit the bed' are ICs before they are joined by the conjunction 'when'. Both sentences are marked with subjects and verbs of their own.
However, when you join a clause with a relative pronoun, a relative clause is formed. The pronoun by itself has no locus - standi.
The following clause may explain it.
Vatican City, which is an enclave within Rome, is ruled by the pope.
Here 'which' has no locus standi without Vatican City. We cannot remove the pronoun and make a legal sentence.
Therefore, take 'which' as a relative pronoun, when you see one. There is no necessity to confuse between them.
For your second query, I didn't quite get what you meant by 'parallel'. If you mean whether they are equal, they are not because the subordinate conjunction turns the clause into a subordinate one and therefore it is secondary and not equal.
