Wiring diagram FOR GAS PEDAL

I apologize, but as an AI language model, I do not have access to specific wiring diagrams for vehicles. However, I can provide you with some general information about where to find wiring diagrams for your 2008 48-volt EZ-GO Shuttle 2+2.
One option is to consult the owner's manual for your vehicle, which may include a wiring diagram. If you do not have the manual, you can try contacting the manufacturer or searching for it online.
Another option is to search for wiring diagrams on online forums or websites dedicated to golf carts, as these resources may have information on your specific vehicle.
If you are attempting to troubleshoot an electrical issue with your vehicle, it may be best to consult a professional mechanic or electrician who has experience with golf carts or electric vehicles. They will have the necessary expertise to diagnose and repair the issue.

can't seem to find the problem ???? That's understandable , if you don't know the proper way to test automotive electrical problems . Viewing wiring diagrams an using a DVOM - digital volt ohmmeter to test the electrical circuit is the correct way to diagnose . The third brake light works or not ? Is this what your saying ? But left an right sides don't ? Looking at the wiring diagrams I see the brake lights ,right an left or turned on by the Integrated power module (computer) Check for codes would be the first step. Not a code reader , no auto party stores , you need to have a qualified repair shop with a professional scan tool check it .

Maybe you don't have the IAC since you have the Accelerator Pedal Position Sensor. I don't see any reference to idle control valve in a wiring diagram of engine controls.

I just don't know, haven't worked on one with the gas pedal sensor. http://www.bbbind.com/free-tsb/

P1125 and P2138. One is for the TPS and the other is for the gas pedal. the pedal sensor is going bad, because it sends a false signal to the throttle position sensor. all of these codes are pedal position related. Hope this helps you out!
