This thread will document all of the connectors in a 2006 WRX Sedan with

• auto HVAC
• manual transmission
• no sunroof
• no heated wipers
• no heated seats.

Please note, the wagon has slightly different wiring in certain areas as does the manual HVAC model (found on the TR model for 2006). Non turbo cars (imprezas) are also slightly different. Specific wire colors sometimes change as do the existence of certain connectors.

Objective:

Retain:

• front door sensors
• keyless entry
• interior overhead light
• trunk light.

Delete:

• ABS
• power steering
• HVAC
• rear door sensors
• other minor systems

My process:
I use two colors of tape: Red and Green. Green tape indicates a connector is needed. Red tape indicates a connector is not needed. The blue tape in the pictures is where I identified the connector when I originally removed the harness from the car.

Layout of Connector Pictures:
Picture
Connector name (corresponds to ID in wiring diagram)
What it connects to (or what it is in the case of harness to harness connectors)
What to do with it (with optional notes).


The wiring diagrams are separated by system so wiring junctions or spliced wires do not always appear in a single diagram. Trace each wire to confirm it ends where it should or if it terminates at a junction.

Wires to keep are not listed (except for optional systems). The chart only lists wires that can be removed.

This document is best used in conjunction with the 2006 WRX wiring guide.

How to Read the Document
The first column
*: indicates to check the notes
?: Indicates I'm not 100% sure it can be deleted
OPT: indicates an optional delete/keep (example: power mirrors)

Connector: Name of the connector

Fully remove: States if the connector can be fully removed (yes)

Total Pins: Total pin locations on diagram (not necessarily all populated)

Pin: What pin number this row refers to

Wire color: Standard Subaru color chart indicating color of wire at that connector at that pin. Capitals indicate new color, lowercase indicates 2 letter color code. Second letter(s) = stripe. example: BOr = Black wire with Orange stripe, RY = red wire yellow stripe.

Mating connector: ID of mating connector if it fully connects to a different connector

Function: What it does.

Notes: Optional info relating to OPT components or if you need to cut the wire at a junction and not fully remove it.

As always, perform this work at your own risk. I assume no liability for mistakes in this writeup, bad suggestions, or angry significant others as you try to have the smallest harness possible and spend too much time in the garage.
