Am I wrong or is this contrary? Can someone help me so I can wire the injectors? Mine Are for BMW if I remember correctly.

Are you asking about the polarity? It shouldnt matter.

Ya. How do I test for which side is +?

Doesn't matter, not polarized. 1 side with 12V, the other is grounded to ECU. ECU triggers them by grounding them.

On the injector? The polarity doesnt matter. Just pick a side and keep them consistent from one injector to the next. It's just a coil, so shouldnt matter what direction the current is traveling.

Injectors are not polarized. The wiring is often polarized and sometimes there is a + mark or other indicator. This is purely for following a wiring diagram.
