Also, anybody know which color wires you splice them into to make them signals? A good thing to go by is that they should be lined up with the vertical center of the headlight and just strait back from there on the fender. Just in case it is different on the 5th gens.

 

Size of hole, maybe... but not the location.

 

Well, I would think the markers are the same. I can't see Honda making diff size side markers for every generation of car they made. But good point. I would make my own outline anyway even if I was using the exact same side markers from that site.

 

the 5g and the 6g civic jdm sidemarkers r different so r the locations. ask a member here by the name of westcoaststyle, he put em in the correct, or damn near 99% correct location for his 5g sedan. mines on my 5g hatch r in the right location cuz i got jdm fenders.

 

I would say just eyeball it,unlessyour showing it,no one is gonna be able to tell.
I eyeballed mine and measured somewhat,mine came out nice.
As for splicing,it was just a trial/error thing for me to find the wire that controls it when you turn as opposed to having it on all the time.I mean there are only 3 wires going into your corner light,one being a ground so you have a 50/50 shot of getting the right wire the first time.
