Default Wiring diagrams????

Im currently doing an engine swap into my 02 wrx with a JDM V8 motor and tranny with dccd.

The only problem is that i dont have the diagrams for all the wiring. I need the wiring diagrams for the engine (using the wrx harness etc), and the diagram for wiring the dccd and tranny.

I also know that with the engine i need to run 8 extra wires for the AVCS to work, and i need the diagrams for that also. I think i can find that though, i just need to remember where i saw it last time. And i will try some more searching of the forum.

Any help as to where i could get this info would be great. Thanks.

-John

Taken from www.wrxworld.com:

These instructions are for hooking up the JDM/UK/AUS STI AVCS Variable Valve system in a USDM WRX. These instructions assume you have an STI AVCS capable ECU, as well as AVCS heads. These pinouts were provided by Al Friedman from i-club, who paid to have someone translate these pages. He mapped the colors to the correct pins and functions, and provided the first instance of AVCS on the new US WRX. Big thanks to Al for all of the pioneering work!

AVCS Hookup

Pin Layout for Connector B84/E84 (Jap/US)

JapPin#/USPin#/JapColor Desc

1/76 GND
2/75[W] AVCS R+ Sensor
3/74[G] AVCS R- Sensor
4/73[Y] TGV R Open
5/72[YG] TGV R Close
6/71[RB] AVCS R+ Solenoid

7/82[BG] MAF Sensor -
8/81 MAF Shield
9/80[R] AVCS L+ Sensor
10/79[LR] TGV L Close
11/78[YL] TGV L Open
12/77[GW] AVCS R- Solenoid

13/87[G] MAF Sensor +
14/86[SB] AVCS Shield
15/85[b] AVCS L- Sensor
16/84[GB] AVCS L- Solenoid
17/83[RW] AVCS L+ Solenoid

Black Plus (Drivers Side) Color Conversion (engine to ecu harness colors)

Red/Black -> Green/Black [R+ Sol]
Green/White -> White/Black [R- Sol]
Red/White -> Blue/Black [L+ Sol]
Green/Black -> Yellow/Black [L- Sol]

Grey Plug (Passenger Side) Color Conversion (engine to ecu harness colors)

White -> Green [R- Sensor]
Orange -> White [R+ Sensor]
White/Blue -> Black [L- Sensor]
Orange/Blue -> Red [L+ Sensor]


The above colors correspond to the colors of the "STI" engine harness. If you have the AVCS heads without the engine harness, you will need to get the correct connectors for the AVCS Solinoid and Cam Sensor.


I haven't seen anything for the DCCD stuff yet but I know some people have done it.

Feel free to post the information so others don't have to go through what you went through.
