I'm really surprised that I have not been able to find this info using the search or Google. I need to know what the wiring diagram is for my custom wiring harnesses, so I can install these Deka 675 cc injectors in my AP2. I have the pigtails for the Dekas (EV1), and I have the OBD2 adapter clips, but I just don't know which wire goes to which pin.

Can any of you post up the details?

 

You haven't found anything because they are non polar (doesn't matter which way you wire it). I always wire the positive/neg to the same side of each connector cause reversing the polarity can technically change dead time slightly but they will work either way.

 

Shoulda picked up a set of ID 1000's from Tony at T1. What are you installing with these new injectors?

 

I find it hard to believe that any DC electro-mechanical device would be non-polar, but I'll take your word for it. Thanks.

I'm just replacing my OEM injectors in my NA build, since they are running over 90% duty. I'm sure I'll try an e85 tune as well.

 

He's right

 

polarity on the injectors does not matter

 

Thanks for the replies. Does anyone know what I'll have to do to install these, aside from wiring? Are they just direct drop-in replacements, or will I have to modify my fuel rail or studs?

 

as long as you have the right o-ring for the rail they should drop in. If anything they may be shorter than the Stock injectors.. i have never had a set of 06+ injectors so i dont know if they are different that the older stuff.

If they are shorter, drill out the bolt hole in the rail to a 12mm hole and use a bolt instead of the stud
