How to un-pin this particular plug end? Different than regular

[Kschep]

I’m curious how I depin this type of plug end to get wires out? ... it doesn’t have a slot for the opposite side regular tab that sticks out slot, but instead has a pyramid looking thing on opposite side than it regularly clips...any help would be appreciated?
I have an mini set of de-pin keys so if there’s one I should be using - thx would be very appreciated info...

I've done a number of those to harvest the connector housing, but had to crush the terminal ends with a pair of needle nose pliers, then push the wires out the front. You'd have to crimp on new terminals, but it's easy with terminals from @Coolerman and a quality crimping tool. I never was able to figure out how to remove those non-destructively.

Insert your removal tool from the back side to push up that triangular part, you will feel it when it is right. You have to get it center on top of the crimped part of the lug, pull the wire snug and hold against the handle of the tool, then just pull out.

Got it !
Right on - I would have never figured that out and probably would have broke it apart like 4cruisers

These are my favorite terminal housings, super easy to dissect.
