Hey there, I see you're having some trouble with the purple part. It sounds like you're unsure if it's supposed to be connected fully or if it's okay as is. Since this was a pre-built item that got upgraded, maybe it's just a design choice. Let me know if you want more advice!
There’s nothing unusual here; it should be okay. In the worst case, the connector handles only the front panel audio jacks, making it clear where a disconnection might occur.
As far as I know that's a 7pin. So if you really want to check the orientation, it might be kind of hard, but you should be able to pull it by wiggling it from side to side why pulling it. Then make sure that you insert back where the 7pins are inserted to the once that has a wire and has a connection.
