That yellow circle is just vaccum lines. If you had to swap the TPS over, I bet the flat blade on the end of the throttle shaft that goes into the TPS is one rotation off. I put a TPS on a long time ago, and had to twist the TPS a bit to get it on, and when I had it all bolted up, it was actually holding the throttole open a very small ammount. Take a look in your throttle body, and see if the butterfly is being held open at all. If not, then loosen the screws on the TPS, and turn it ever so slightly until you hear the idle drop to a good level. If the idle never drops, and the resistances on the TPS all show good, then I would start spraying carb cleaner around while the engine is running (spray where any gasket is, or vaccum connection) and listen for RPM changes. Good luck!
