Injector wiring, polarity?

I'm changing the LQ truck injectors for LS1 injectors.
I'm ordering the LS injector plugs from summit.

Which is the + and - pin on the LS injectors?

it really doesnt matter, they are a basic coil and polarity doesnt matter to the injector

Are you saying it wont shoot fuel out of the top of the injector if I wire it backwards?

It's kind of dark in my garage....
Here, hold this lighter over the engine and see if it sprays fuel while I crank the engine.
