I cant find the diagram on the website. I have searched but no luck any help would be appreciated thanks.

 

ok nobody i guess

 

Apex-1's Website has the wiring diagrams for that. I think it's a japanese translate though. When I wired my then D15 civic with an afc2 I had to use the B18 ecu pinout. Just match your ecu pin layout with the one in the instructions. It took me about 20 minutes to install, very easy.
