Hey, so I have a Power FC L-Jetro for a s13 redtop sr. I recently bought the apexi boost control kit 415-A001 which turns out is the wrong boost control kit. The difference being in the plugs. My power fc has a 5 pin plug for boost control kit. But the kit I got is only a 3 pin plug. I did some research and found this… [Apexi PowerFC FAQ](http://paulr33.skylinesaustralia.com/docs/powerfc-faq/powerfc-faq.htm#38) So clearly the boost control kit I got was type 1. So what I tried to do was, shave down the 3 pin plug to fit onto the first 3 pins. And then I got a 2 pin plug and wired up the solenoid. Everything should be right. It goes… 1st pin : MAP power 2nd pin: MAP signal 3rd pin: MAP Ground 4th pin: Solenoid Positive 5th pin: Solenoid Negative So it should basically look like the harness on the proper kit. ![http://paulr33.skylinesaustralia.com/docs/powerfc-faq/PFC_BCK.jpg](http://paulr33.skylinesaustralia.com/docs/powerfc-faq/PFC_BCK.jpg) After wiring it up and plugging it into the Power FC. I went into ETC and then FUNCTION SELECT and I turn the Boost control Kit to ON which is the japanese symbol without the +sign. But after doing that, when I go to Boost reading it stays the same and shows… Boost: ----- Any ideas as to how I can get this to work? Much appreciated. Jon ---

i just took a multi meter to the 5 pins and got… 1st pin: Power 2nd pin: not sure, should be signal but don’t know how to test for that 3rd pin: Ground 4th pin: Power 5th pin: is supposed to be ground but doesn’t seem to show anything. can anyone shed any light onto my situation? Jon ---

Just called apexi… and they said the map sensors are the same on the kit that i have 415-A001 and the kit I needed 415-A013. And in fact, the difference between the kits is only the end plug. And even with them saying that, they told me how I modded my plug would work as well. So this leads me to believe that maybe the map sensor is faulty. Any ideas as to how i can check if it’s faulty? What would I need? Thanks. Jon ---

A volt meter and some compresser air. 🙂 Any idea on where to pick up the three pin plug? Other then from apexi? ---

since i don’t have a compressor, could i just run the car and measure the green signal wire with a multimeter? if the car is running and the map sensor is working it should get a reading right? And as for where you can get the harness… i found this site that sells optional power fc parts. They sell both the 3 pin as well as the 5 pin harness.
