Hogan029 Posted October 17, 2015 Share Posted October 17, 2015 (edited) Hi all, Long story short is that I have a JDM intake which I am trying to use the North American harness on. I was wondering if anyone has a harness diagram to show which plug goes where. I know that I might have to do some modification on to the harness in order to make it work but I am not opposed to doing that. If someone has a pinout diagram, I could trace the lines perhaps? This is my intake. I still have the old harness on it still. Any thought or comments would be appreciated. Cheers, Ryan Edited October 17, 2015 by Hogan029 Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 17, 2015 Share Posted October 17, 2015 Starting at the top. Greyish plug: cam sensor Two grey plugs: fuel injectors 2&4 Greyish plug, 3 pins: ignition coil or IAC maybe White plug, 2 pins, single wire: knock sensor Black plug: Throttle sensor Small light grey plug, 3 pin: ignition coil or IAC Orange plug: Coolant temp sensor for ECU Single spade next to it: temp sensor for guage Blue plug: Evap purge solenoid (under number 3 runner) Brown plug: crank sensor Single wire black spade connector: oil pressure switch Two grey plugs at bottom: injectors 1&3 Open eyelet: ECU ground, goes on top of the manifold. There will probably need to be some lengthening done to get the IAC plugged in. 1 Quote Link to comment Share on other sites More sharing options...

Hogan029 Posted October 17, 2015 Author Share Posted October 17, 2015 Hey thanks for the reply. There are two that I was confused with. I labeled everything so that it was clear for me and future learners. 1 Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 18, 2015 Share Posted October 18, 2015 (edited) Orangey-brownish plug on the left is the CTS for the ECU. On the right, brownish plug by the oil pressure plug, is crank sensor. Fuel injector plugs you'll need to look at a wire diagram for that year and see which color wire goes to which injector. Power wire is common. The ground side goes to the ECU so ground wires will be different color for each injector. Also, I'm thinking now that the light grey plug on the left with the shorter lead is for the IAC since that should be close to the TPS on the 98 engine. The darker grey plug with the longer lead is probably for the ignition coil which is normally mounted top center of the manifold.

3Pin Posted October 19, 2015 Share Posted October 19, 2015 Wouldn't it be a lot easier to just use a 2.5 USA intake? I got a spare if you are interested? Quote Link to comment Share on other sites More sharing options...
Hogan029 Posted November 8, 2015 Author Share Posted November 8, 2015 Does anyone have a pin diagram so that I can make sure what is what? just looking for a pin diagram for the connecter to the main harness Quote Link to comment Share on other sites More sharing options...

Hogan029 Posted November 8, 2015 Author Share Posted November 8, 2015 Also my JDM power steering pump has a connector on it, I cant seem to figure out what it should connect to as there is no plug on the US harness Quote Link to comment Share on other sites More sharing options...
ocei77 Posted November 9, 2015 Share Posted November 9, 2015 The'02 Forester and other 2.5 SOHC have that PS plug. Don't know when they started or how much across the line it goes.. Do search for FSM. Download and go to the Electrical section and you'll find the pinouts. O. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted November 9, 2015 Share Posted November 9, 2015 The later pumps have a speed sensor in them. It's not necessary for your setup. You can leave the sensor unplugged. Quote Link to comment Share on other sites More sharing options...
