My money's on the black,brown,yellow trio. If it's anything like the 0280120402, then black is +5, brn is gnd, yellow is signal out. A multimeter will tell you for sure.

The resistance between the 5 volt and ground pins will remain constant.
The resistance between the ground and signal pins will be low with the throttle closed and high with the throttle wide open.
The resistance between the 5 volt and signal pins will be high with the throttle closed and low with the throttle wide open.
Using these rules, you can establish which pin on the TPS goes to which wire.
