I followed the diagram above but kind of lost. Don't flame me this is my first time doing this thing so can someone help me, can't seem to figure this out. This is wiring for e5 to j4 ecu, since you have to move pin #9 to #25 where does pin #25 go to? Also what is going into pin 102, 104, 111 and 115 from the image below? I want to have a/c so do i move #106 to #11, because in the direction the last step is from #10 to #11, but i don't have pin #10(green/yellow). My green/yellow is at 106 and it is bigger then the smaller #11 pin which i can't plug in. Please help out.

Quick question: Why are you rewiring? I'm guessing it's because you have a kouki S13 blacktop motor and ECU and a non-kouki (i.e. redtop) wiring harness, and want to make them work with each other?

I'm not sure if you know, but a #62 ECU will run a kouki S13 blacktop motor just fine. The only real difference is a very slightly different fuel/timing map with the J4 ECU (I believe to increase mid-range a little bit), so you'd just be running a non-kouki fuel/timing map. You probably wouldn't know the difference.

Just throwing that out there, in case it helps.

oh i have a j4 ecu and no kouki harness, as of right now i really don't know if my motor is a kouki s13 sr or not. If you know how to tell the kouki s13 sr motor from the others lmk.

You don't need 2 threads about this.

I helped you in the other thread.

I'm going to ask the mod to delete this one.
