'04 has throttle by wire and with this there are 2 tps circuits. the two redundant circuits are required for safety margin. One circuit starts high and moves low as the throttle opens, the other circuit starts low and moves high as the throttle opens. I don't have any wiring diagrams so I can't by of more help. BTW, I think the run off a 5 V supply. So the 4 wires should be +5V, ground and the 2 signal wires.
