Default Wiring 2002 WRX Harness to V7 207 ECU

I have created a spreadsheet comparing these two pin outs and have ran into a problem with the Fuel Pressure Sensor Signal Wire. On the WRX it is saying that it is B135 / 15 (B15) and it is no where to be found on the 207 Manual. Any help would be appreciated.

Here is a link to the Pin-Outs I am using.
2002 WRX: http://www.northursalia.com/modifica...ng/wrxpin.html
and
V7 207 : https://docs.google.com/open?id=0By8...I0YzNmMzcwNGZi

So far I am thinking these are the changes I have to make
Switch C15 to C16
splice A5 off of a16
and I'm having problems with Changing B15 to B8 since B8 is already something.

Any help is greatly appreciated.

if your putting a v7 jdm ej207 into a 2002 usdm wrx all you need to do is plug it all in. ECU will plug in and match up and the head connectors as well. The only difference is they add 8 wires (4 passenger side, 4 drivers side) for AVCS in the JDM cars. IAperformance sells a plug and play kit you just remove the pin blocks and install the wires running 4 from the passenger head pin block and 4 from the drivers one right to the ECU. they use all the same pin blocks just the USDM cars they left those spots for the AVCS empty. its about the easiest swap you can do.

This. It's a plug and play affair.

Idk guys ... I have looked at pin outs for both and found several differences. See these links please. I pray it is plug and play but please tell me the validity of these links


USDM 02 WRX: NorthUrsalia.com: 2002-2003 WRX ECU Pinouts
JDM 2002 STi: http://bebeu.free.fr/43R-STi_Eng.pdf

and these are the differences between the two in spreadsheet form from the links above

I'll say it again too....its plug and play.

You can run/repin the AVCS through the TGV wires since they are shielded and go directly to the ECU, or get the IAP harness kit like N8WRX mentioned. Besides the AVCS the only other difference is the JDM EJ207 does not run one of the sensors on the TB. I think its the temp sensor or something, all that you need to do with that is leave it unplugged. If you pin out all the pins on the ECU in the JDM vs USDM harnesses with the diagrams you will see the holes where the AVCS goes is empty on the USDM harness.

.....I dont like the www.northursalia.com thing its not helpful at all. cross reference the EJ207 info on here....

Sorry to be repetitive and moronic I just want to be sure, here is what I'm doing. Putting an 02 WRX harness into a v7 EJ 207 ECU with an IA performance AVCS kit. All of this is being hooked up to a v7 207 engine with v8 207 heads in an RS 2.5. The wiring combo of 02 WRX harness in v7 207 ECU should be plug and play?

if your in a RS and using the stock Chassis harness then no its not plug and play and wiring is involved. If you are in a 2002-2003 WRX with the stock chassis harness and the stock ej207 engine harness it is as we described plug and play. There are 2 harnesses at work here chassis and engine. as far as ECU you can plug in a v7, v8, usdm wrx, and have them all work. the usdm wrx will not run avcs, either jdm ecu will.

The diagram that you are looking at is more than likely a UK diagram and yes there are a few differences. The JDM pinout is the same as the US with the exception of the AVCS.

^^Im getting ready to do the same thing pretty much. Ive been reading over and over all kinds of stuff and I wish someone did a write up on a how to or something. Im finding quite a bit of conflicting info.

I dont want to have to buy the ia harness if I dont need it. I have a bugeye and WRX chassis harness, v7 ECU, and v7 engine harness. I also have the WRX engine harness in case I need to cut out some connectors, but I think the v7 harness has them plugged in already. What are the "shielded" wires? Do I just need to repin the factory wires that used to be the TGVs?(on the chassis harness) Shouldnt those be the wires I need to relocate on the harness inside the car?

Sorry to bump this up.

But if you have a 02 wrx and a V7 EJ207 with harness on the engine. You don't need to swap any harnesses? You just drop it in and plug the big connectors in?

You can plug them together and it will run, but you need to repin the TGVs to the AVCS and also add some shielded wires. Easiest way to do this is get the cut chassis harness like I got with mine. I was pleased to find out that the wires took a turn by the cut harness and in fact were whole and complete. Just re pinning necessary at that point!

so this adds the wires for the avcs solenoids by using the TGV wires, what are the other wires for?

The wires you are relocating on the F61 plug are the same wires that you relocate on B84?

These wires you have to add, what are they for? Cam sensors? I cannot find the description for these in the ecu pinout. I would like to know what I am doing before making the swap.

anybody else having an issue where the left avcs stays at 0* jumps to 35* for an instance then back to zero, and the right avcs goes to like 65*?

Also noticed that pin 5 on the light gray plug over he turbo is pin 7 on the DS1 guide...anybody know which is correct? I've tried them both and have the same issue where only L or R avcs works not both.

Im having issues with my v7 swap, Im getting the P0365 code using an

OBD II sensor. I wont get my Tactrix cable in till tomorrow, im hoping it will help shine some more light on the issue. My car idles Rough and stops after 10 seconds. After searching all night yesterday, checking and rechecking wiring, i still cant find the issue.


I used the pic above to repin the ecu and add the 4 wires. Im gonna try moving pin 5 to 7 and see if that fixes my issue...cant make it worse...can it??

Sooo If I looked at the image from import tuner's swap correctly then they are using Pin 7 instead of Pin 5. Just got out from work and will try it for myself when I get home

So I swapped out 5 to 7 and still no luck for me the engine however does run longer before shutting off and noticeably not as rough. My neighbor was asleep by the time I got home so I couldn't borrow his OBD sensor to recheck the codes this time around. Tomorrow I should be receiving my openport in the mail. Hope this at least helps someone somehow

His bout this one fellas, 2004 Wrx. USDM 2.0 harness on an 05sti longblock, but I'm using USDM 2.0 tgvs, intake manifold, cable throttle body and obviously the cam sensor relocation bracket. What do I need to do here? I want to run avcs, I want my 35r tune on my 800cc top feed and fuel tails to actually mak a bit better power down low.... Do I need a jdm sti engine harness and ECU or what. Walk me through this please.
