Datalogging header installment in PR4

Well yea, basically what the title says. I’ve got a pr4-a10 and im trying to install the datalogging header and im not sure where to put it. I’ve been all over pgmfi.org and xenocron reading about chipping obd0’s but what i’ve found is this:

-datalogging header goes into cn1 or cn2 depending on ecu
-it goes into 1-4, 5 is not used.

What i’ve realized on my ecu is that the 1-5 area is not under cn1 or cn2, BUT under cn3.

Maybe i’ve over-looked that it should go into cn3 but i just want to make sure that it should go into there before i start soldering it in.

I can get pics of what i’m talking about tomorrow, but if anyone knows what the hell i’m talking about, please chime in and let me know whats up

Sorry if i’m posting this in the wrong section but i figured FI’d>boost>engine mangagement>ecu>chipping lol iono

It goes on the spot labeled CN3, in spots 1-4

thanks a lot. i looked at it and saw it was in a diff. spot then stated in many forums i’ve been reading in and just wanted to make sure i was putting it in right before i run into problems.
