The throttle position sensor was changed and the wiring is different. If someone could just tell me which wires go where?

Hello, the 2nd picture includes the throttle position sensors and pedal position sensors as well as the throttle motor for moving the throttle plates. All these wires go to the throttle body. Did someone cut the old wires, or what's the story behind the attempted repair? All of these wires go to the engine computer, so you're going to be dealing with 12 or 13 wires at the throttle body. If you could take a picture and post it here so we can get an idea of what you're dealing with it will help a lot. Is the check engine light on as well?

Al514, I needed the diagrams myself the problem my son is having is whenever he comes to a stop about a mile or 2 down the road the car just doesn't want to go anywhere so he has to stop or brake put car into park shut off and start again put it in to drive and it continues to move forward but engine light is on and the codes are referring to a app bad or sensor so we replaced pedal relearned the app and worked erased engine light and everything but came back started again I'm wanting to check voltage received but idk the specifications and what is passing or specifics of voltage.
