you could try that may work.
The other cable you showed is like a brake cable on a bike. It may work, but most likely not.
Main reason behind that is because you will need to find something to keep tension on the cable to hold the rpm steady.
Another thing is that that cable is very flimsy and flexible where as what I got is rigid, I have mine bent in a L shape to hook behind my intake, so its not bolted or screwed to anything. but when I turn it, it pulls my throttle open by hooking on the intake.
If you attach a cable perminatly to your intake, one thing your going to have to take into consideration is the cable will have to move freely with little to no pressure, or you will get a very stiff gas pedal.
which is why I went and did some custom bends in the wire itself to have it always come back to a rest position that will easily slide in and hook up every time
