You can identify the leads with an ohmmeter.
Find the three wires that show a resistance to each other.
Connect the meter to any two. Move the TPS. If the value doesn't change, you've found the Vref and ground. Swap meter around until you find it.
Connect + meter lead to one of those wires you've identified above.
Connect - to the remaining 3rd wire. Move TPS.
If the value goes down, then the + wire is on the Vref and the - lead is on the signal. If the value goes up, the opposite is true.
