When you have more than 3 wires then you have a dual TPS device. So, it gives two throttle position signals to the engine control unit at the same time. More than likely, if the two sensors disagree then the ECU won't act upon either signal - in the name of safety.
I don't know anything about your particular TPS so I certainly can't give you specific pins or color codes of the wires for troubleshooting. That said, you can experiment with a multi-meter and figure out which are which and then compare the two variable resistor outputs. If this is foreign to you then you can take it to someone that can do it for you. Or get someone to bring a diagnostic tool to your rig. Or, as I previously mentioned, if you have a Silverleaf dash display then it can show you the throttle position that the Cummins ECU is seeing.
