Sent. Seller returned the same guide with a different filename.

Compare the document revision inside it, not the filename. If the same wrong pictures remain, show one paired example of guide versus supplied connection and ask them to answer that specific mismatch.

We had a packing list mistaken for an installation reference. Ask who on their technical side is confirming applicability, Aisha, not just forwarding the attachment.

Internal revision unchanged. The paired example has now reached their technical contact. Setup stays unpowered.

Good. Keep that old guide out of the bench folder while they answer. Somebody covering your absence shouldn't have to rediscover which document was sent just to make the email go away.

Julia's folder point is useful. Preserve the old attachment with the query, but do not present it as the current installation instruction.

Aisha, have they confirmed the supplied cable is intended for this package? The manual mismatch might not be the only mismatch.

Yes, Elena. Correct documentation for the wrong item would be an oddly thorough way to stay stuck.

Technical contact confirms the package and cable identities together. They have sent an applicable guide revision showing these connections. Installer is checking it against the delivered equipment before proceeding.

Make that confirmed revision the one the installer hands over too. The old guide shouldn't make a comeback when someone searches the purchase email.

Has the installer completed that comparison yet, Aisha?
