Wiring Guide: 06 WRX Sedan with Auto AC/HVAC

Frank 818 would be proud of me though.

AB60: ABS to Bulkhead wiring
Delete


Antenna plugs
Various wires coming off the antenna amplifier. The banana plug goes into the radio to provide a signal
Delete if not using the radio (comes off with amp when unplugged)


B32: Turn Signal


B50, Blower Fan Relay
Relay for blower fan on HVAC
Should be able to delete (need to confirm)


B51, B271 (blue plugs): Fuse Box plugs


B65: Stop Light Switch
Connects to brake pedal (?)

That made me laugh!

I need the harness that goes from the engine/motor connecters to the ECU (and associated wires) Is it one harness?

Does the harness I need have everything I need to connect a Cobb accessport V3 also?

Also, I am in process of simplifying my harness. Much of it is yellow air bag circuit. Since I will not be using this circuit, can I peel all the yellow wires back to source and eliminate?

More or less. It gets tricky as sometimes they wrap with yellow, then switch to black, then combine it with another, then split it. Best bet is to find a FSM and get the wiring diagram. The hard part is identifying all the connectors (which I've done here). The easier part is tracing one part to another and cutting it off.

On my 06 It's multiple. There's the front engine harness that attaches to the bulkhead harness on the driver side but some connectors (02, boost solenoid, MAF, rear 02, speed, trans) are part of the bulkhead harness itself.

Should be able to connect to a COBB. I'm using a V2. I'm only cutting off things that no longer exist (HVAC, airbags, ABS) and even if I didn't cut them out wouldn't do anythign.

Edited a bunch of the previously reserved posts. If I get a chance, I'll work on the front harness tonight. I need to move some trees though. Thankfully, the builder told me my property line was 20 feet past where it really is so I get to dig up and move trees I planted 4 years ago. [/sarcasm].

Once I finish documenting all of the connectors, I'll start tracing what can be cut off and where and do my best to document that. If it becomes too tedious, I may fall off in my documentation. The end goal is to have a set of instructions that anyone with an 06 WRX sedan/autoHVAC/nosunroof/Manualtrans can pick up and follow steps A to Z with minimal thought input.

I would tell the builder that he needs to move them since he did not tell you this before or at least help you move them!

Ha!! Just saw this!
Of course I am!! Keep up the great work! I know you are far from home right now, but you'll be back to continue that work.


What were we discussing back then?
