92' 3.1L swap

[xLeGeNDx]

im wonderig if i should just run a new wire through there, becuase the only wire thats connected to that is a grey one and the battery terminal wire

EDIT: I was able to get one injector to give off a little bit of gas but the other 5 are inoperable until a voltage was applied directly from the battery, but now im getting 12v across both injector wires on all 6 injectors
