Hello everyone can i check with you would there be any major problems or any problems at all if my arranged my plug caps wrongly? originally should be 1|2|3|4 but might have replaced them as such 1|2|4|3 . If so how do i tell if they are put back correctly or wrongly? is there any sounds or effect that would appear such that i could tell?

if i'm not wrong, it should be 1 & 4, 2 & 3... please change back asap!
the only way is to pull off the tank & confirm.
