Solenoid to Motorized Fuel Tank Selector Valve

[Dukagora]

79 C20 454 Crew Cab.

I am trying to figure out the wiring. How this all works. I have read a lot and thought I got it only to realize several times that something else I read confused me. I know the system is simple, but still not getting it.

I have a switch I thought I needed - part # S9002(works on O'reilly website for sure). I have read that if the switch says "push to fully depress", its for a solenoid valve. If not it will work with the motorized valve. Is this correct? If not correct....

Valve is the 6 port that used the 5 pin connector with A-E having pins in it.

I had expected to have to use the switch in the link to make things work.

If you skip to 8:42 of this video, is the wiring correct on this switch? Also, are the instructions provided in this video accurate? I assume so but just don't have the experience/knowledge to be sure.

If the video in the link is accurate, how do you get the signal from the sending units for gauge levels? I have attached photos of what I currently have. Do I need to cut the blue wire off the factory connector and stick it to the corresponding, apologies for incorrect terminology, terminal on the switch? Same for pink wire from passenger? "Middle terminals".

I have a pink wire coming off of the passenger side tank.
I have a blue wire coming off the drivers side tank.

The Switch was working correctly as there was gas in the drivers tank when I dropped from the truck.

Attached pics are probably obvious for most of you, but, the one in hand is to the switch at the dash. The other is inside cab at firewall.

Sorry I know there are a lot of threads out there and Hatzie for an example, has been pretty thorough.
