How does this connector come apart? (1971 Duster)

Had to go there! :rofl:
Kinda hard to use that method while standing on my head to work under the dash. Lifting the tab did the trick. I cleaned the connector (which wasn’t in bad shape at all) and put things back together. I finally traced the intermittent connection to the black wire adjacent to the yellow wire on the end. Seems that there’s an intermittent connection between the incoming wire and the male pin. There does not seem to be a non-destructive way to remove and repair this pin. Is there a tool to remove the pin from the connector? If not - I may just need to cut the black wire and make a by-pass connection. This black wire feeds half of the fuse box. It is currently working ok but I don’t trust it.
