It's more involved than just the blue and green wires being switched. If you notice in the video, the indicator lights on the remote controller are backwards as well. IIRC the two motor wires are reversed and the molex plugs for the microswitches are as well.
At least that is what I did to reverse the indicator lights so green was diverging and red was straight through.
Either the sentence or the turnout needs some rewiring it seems
Green is supposed to be straight, red for diverging.
This thread does have some good wide angle shots putting it all in great perspective. I've seen tons of close ups, that's old (still nice tight focus on those too. I wish mine was better at micro subjects).
I usually use hat pins to get at plug tabs. They tend to do less critical damage even if it's a spastic oops moment and a boody finger vs plug. Thick enough to be tack hammered though melted plugs, etc. ...and even when it does some damage to plug shape, etc, it usually leaves enough plug intact to function again. It's damage ability to the terminal is limited by it's own size too.
Most plugs use a tool specific to the plug style. Some tools are more generic, some more proprietary. Mostly it's a round or square telescoping tube that slides beteen plug and terminal and presses the tabs down, then as you keep pushing past the tools spring pressure, a slug slides into the tube and pushes the terminal out of the plug.
Just like an apple coring tool or peeler, it seems unnecessary until you know how great they can actually be to use to bake even one pie. Then suddenly it's recalled how worth it they can be ..
Wire gauge tools and wire welding tip cleaners work well too sometimes as do small nails inserted into the sm slots/holes next to the terminal.
Very few terminal releases happen from the wire side of terminal/plugs.
