Just arrived from Amazon, so I haven't used them yet.
BJSIA Electrical Disconnect Pliers for Cars, Automotive Hose & Fuel Line Disconnect Tools with Connector Pliers for Push Tab Style Plugs (Straight head+bend) $14/pair
I've tried three times now to get my throttle pedal electric connector freed. Last time I tried, I noticed a steady drip, drip noise on my Tuxmat while my head was laying on it.
Wiggled my way out and found a good gash in my forearm while trying to work the connector off. There is not enough room to get both hands on it (because of the clutch and brake pedals. So, my solution is to throw some money at some tools and try again.

If anyone knows of better tools for the purpose...let me know.
