Two TPS from S5 TII, different wire colors?!

[jimmydanny]

I got a  TPS from a guy in the US, for S5 TII, and here two wires were yellow, I suspect the 12V.

On my old one (which I now measured 1-5k and 5-1k ohm as it should be) had one orange and one yellow to the full and narrow range.

One is also labeled AAD, the other AAB.

Anyone got any wise words?
