Vortex Sound Research

Long story short: got a bunch of modules in today and re-arranged my case. Thought one of the new modules shipped without a cable, I dont really use the A-119 so I took its cable and plugged it into the new module. Afterwards I found another cable and still had room for the A-119 so I plugged in the cable, but it was backwards.

I'm using an Intellijel 7U case. With my limited knowledge of electricity, this event shouldn't affect the other modules in the case right? They all sound exactly the same and perform the same but after smoking a module, I'm paranoid.
