Does anyone know the STI 2.5LCoil pinout?
I'm trying to use an aftermarket (Redline Weber) ECU with my 2004 WRX STI 2.5L for off-road use.
I seem to have everything figured out and wired except but I can't figure out the 3 wires on the coils? There are different wires on the front coils and rear coils (mounted on the plugs) I think they should be +, - and Trigger ( ground to fire coil). I looked through the service manual ( I downloaded) - no luck. Any idea if this is the same as the JDM EJ20? Any help is greatly appreciated - thanks

Are you talking about the coil packs on the STi and/or WRX wether they are the same or not? I believe there are only three wires that go to coil pack.
One is + (part of connector) One is - (part of connector) One is the current to zap the trigger Cheers, Bill Knose I-Speed USA www.i-speed.us |

Thanks for the info - But I need specifics
Yes the packs have 3 wires but I cannot figure out which one is the positive (+) , negative (-) and trigger (~). That is my issue.
There must be a manual somewhere that gives the pinout so you can test the coil? I'm thinking Chilton or Alldata? I'm looking for a descriptionlike this so I can figure out how to wire the coils: put +12 on the Black/yellow wire and ground the Blue/white wire, Trigger the Green/yellow to test spark... Someone must have used an aftermarket ECU with an EJ20 JDM or the 04 STI? Thanks again Alex |

According to this drawing: Pin 3 of all 4 igniters are tied together and are fed from the fuseblock by fuse # 11. Wirecolor for all 4 at the igniter connector is given as RY (Red/Yellow - you did not mention any Red wires ??). Pin 2 is the trigger for each cylinder. Wirecolor varies by cyl (GY, LY, WY, Y) (L = Blue) Pin 1 is tied together for cyls 1&3 and 2&4, and both of these pairs end up tied together at the ground block. Wire color is BY (Black/Yellow). IF the wire colors you are seeing do not match this documentation, can you see pin numbers? |

Thank you... Pinout is great
This information is exactly what I needed, and the color code matches perfectly.
Looks like I'll have it running this weekend ! Thank you |
