Default Wiper motor plug

Been putting off asking this because it seems so elementary, but how the hell does the top plug on the wiper motor un plug on a '90? I unplugged the one closest to the driver side with no issue, but no matter how I depress that tab on the top one, it won't budge. Someone help an old weak man out.

Hm. Having a hard time remembering the answer to this because it's been so long since I've had that unplugged on my own '90, but I think (and I might be wrong) there's a notch on the bottom of the connector that you have to push in or pull out. I think...

Bad part is, I'm just trying to see if it's functional. Low and high speed works fine, washer pump works fine and park is good. However, when I cut it on to Delay, the wipers are on Low speed, no matter the delay setting.
