help with the overboost system (wires colors)

[kassus]

hi

in this photo i show the actual conection of the wires to the electrovavles. actually the yellow wire connect to the left electrovavle, but i dont know if this is the original position.

to make this comprobation i need someone tell me if its correct connected or is inverse. for check this, you only must say me if the yellow wire is going to the left or to the right electrovavle.
