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.

 

You can get a copy of the FSM for the color code. Try www.rx7city.com

 

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

 

I found it in the wiring diagram. Thanks,

 

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.
