Digital Multi-Meter will tell you for sure.
Hold throttle 1/2 open. Probe (2) wires. If +5V, then your black lead is on Sensor Ground and red lead is on Sensor V+. If + ~2.5V, then black lead is on Sensor Ground, and red lead is on the TPS input to the UMU. Etc. If you cannot follow the logic, then probe until you get those two readings, and you will have your answers. Note: probe the Back of the terminals by using a thin probe slid next to the wire until the terminal is reached.
Best I can tell from diagrams is:
Blk/Red is Sensor Ground
Grn/Blk is Signal to ECU
Grn/Red is 5V
