Can anyone help me in telling me/identifying the pinout or colour of the wire on the ecu loom for :

*Ecu boost control
*ECU 12v
*ECU fuel injection signal

cheers

Don't know if they are accurate, but these might help:

yep got it,

to answer my own question - 2004/5 WRX STi ECU (US version)

1. Wastegate control solenoid valve - B134 - pin 32.
2. Ignition switch (10-13v) - B137 - pin 15
3. Fuel injector #1 - B136 - pin 6

bump


the above diagram seems like its a 2005 spec STi diagram


Does anyone have information on a 03/04 STi (aussie/jap) ecu?

So far, the closest pins that I got that look like the blocks on my ecu are:

*Ignition 12v (i got pin 5, B134)
*Boost control solenoid (i got pin 24, B84)
*Injector #1 signal (i got pin 6, B137)

(from a 2004 US WRX)

btw - might want to make this link a sticky:

2004 STi service manual

doesnt apply to 03/04 ecu tho.

ok finally solved it!!

- Fuel injectors: #1 E1(pink-B84), #2 D6(PL-B137), #3 D5(PB-B137) and #4 D4(PG-B137).

- Wastegate: E24(BW-E84)

The fuel injectors show ~12v upon key-turn 2 (pre crank). you must enter the pin code in the brant to show the voltage!!
Otherwise - it limits it to ~2.5v - as I learnt the hard way tearing out my hair.


Below is the Autronic SM4 wiring diagram that helped me (relevant to ADM 03/04 WRX STi's)

**note block numbers are displayed different from autronic to subaru wiring diagrams (I have used Subaru pin blocks above)

Hi all,

Sorry to bump an old thread. I'm just having a bit of trouble getting my defi vsd installed. I've been searching all night for AUDM STI ecu pin outs and so far the best I've found is this (off wrx.com.au)




I'm needing the following:


I had a friend translate for me:
orange - 12V constant
yellow - illumination
red - ignition
black - ground
blue – tacho
green – speed in/out

Can anyone confirm that pin out F8A above is indeed correct for an 03 (MY04) AUDM STI?

Also, I still need 12V constant, illumination, and speedo – any ideas?

Thanks,
Tin
