So I got my timer but the directions are in japanese so I was wondering if any one knows what is what? I also have a GReddy wiring harness for it. I did search and couldnt find it. If any one could help me out tha would be great.

 

ok so I found a Install diagram for the Timer but I still need to know what the 3 leads are for on the wiring harness.

 

apexi's site should have the manual online.

 

The FD wirring connector seems to be generic among the turbo timmers. I've had the greddy, blitz and now the Apexi all installed with the same plug and play connector. The Apexi web site has the installation instructions in english on there web site. The three wires should be black=ground, gray with stipe=emergency brake, and the thrid one color forgotten=O2 sensor. It's been awhile so the gray one and the other unknown color color may be the other way around.

the extra 3 leads are not used if you have the harness, ar you talking about the extra red blue green wires? if so just leave em alone, and just plug the harness up and ground it
