Engine bay fuse panel help

[npace]

Sorry if I'm posting in the wrong spot, but I need help de-pinning the giant connector that goes to the fuse panel / relay panel in the engine bay. I was able to get it started but now it's just sitting there. For reference, here's a pic of the connector I'm talking about, it's the one on the left:

If anyone can help, I would really appreciate it.

Not for sure but those blue parts are typically some type of lock. Can't remember user name but somebody has a shaved engine bay so they might have had to take these apart...

So I got it figured out, mostly. The purple section is a lock, but that's undone. I got all but the two large wires out, and it seems no matter what I do I can't get them to release. Can't figure out if there's a different terminal removal tool or what.
