Default Reverse Intake - Wiring Changes?

Hello I am wanting to reverse the intake on my swap. Will I need to switch any wiring around? I thought about swapping the coils from the left and right sides, and orienting the injector plugs as if the engine itself was reversed, but I'm not sure and search here and Google for "reverse intake wiring LS" is not helpful at all

TIA.

Leave coil/injector wiring over their respective cylinders. IOW, pull injector harnesses off injectors and lay down near original position, pull manifold sand reinstall backwards. Reinstall injector harnesses to the injectors they NOW align with. Basically ONLY the manifold and injectors move. NOT the wiring, as it is cylinder oriented.

Oh ok, interesting.

I figured since Cyl 1 and 8 injector placement flips, that you would need to switch the signal wire for those, and others and you would have to switch the coils left and right.

So wiring is the same. The only thing changing is the orientation of the intake and technically the injectors, but they keep their placement in the rails?

The engine does not "care" which way the manifold is pointed, or which injectors are where, as long as the wiring is where it was before the manifold got turned. So yes, what you say is basically true.
