S4 Injector wires???
Hey, does anyone know which of the two wires from the injector is the positive wire? I have a 88 that I am putting some low imp injectors in and some high imp s5 injectors. I'm just trying to figure out which wire has the positive voltage going through it.

The wire that is a common color for all 4 injectors will be the hot wire.

According to the diagram I just read the b/y wire is shared by all injectors and it is the negative wire. The other wire is the positive one and it has different variations.
