I am going through Chapter 18: fuel injection.  I just went and looked at my 2007 5.3l.  It looks like there are 4 wires to each injector.  So (+) and control.  What would the other 2 wires be?

Thank you

I think you may be looking at an ignition coil because I can't think of an injector with more than 2 wires.

Is this what you saw maybe?
