on my honda civic the color coding on the injector wire are:
cylinder #4 - blk/yel & yel
cylinder #3 - blk/yel & blue
cylinder #2 - blk/yel & red
cylinder #1 - blk/yel & brown

now, cylinder 1 & 2 have shorter wire and are very close to each other and i'm installing my 450cc dsm injectors. my question is, what if i accidentally switch the blk/yel of cylinder #2 to #1 and the blk/yel from #1 to #2 since they are very close to each other and i wasn't able to label it, will that cause any problem?

again, only the blk/yel were to be switched accidentally but the red is still wired to cylinder #2 injector and brown is still wired to cylinder #1.

any help will be appreciated.

 

That will be fine, the yellow/blacks dont matter what injector they go to as long as they each go to one.
