Is this what you're talking about?

Yes, it's the one by the battery with the brown and black plugs. Both are missing.

That sucks man! You can look into this harness, which promises to add the missing wires, so you can use your USDM engine harness. Supposedly it's for motors that didn't come with a complete harness...

... it is different from their AVCS bulkhead wiring kit, which most people need to wire up their ECUs.

Thanks! You just saved the day!

Where can one sign up for a lap?? You sure those rates are semi-accurate?

After a quick search I saw one lap in a Suzuki Swift Sport was 99 euro and it goes up from there.

It's balls on accurate, certified by NASA engineers.

That's the price for using your own car.

[Paul]

Ooo. I thought that was the price of renting/running a STI down the track...lol

That makes alot more sense and seems reasonable

This is your best option, less messy. Although this would mean having to take off TWO intake manifolds to swap over the WRX harness. So while you're at it, get a new turbo inlet so you don't have to remove the IM again in te future. I wish I had done that in the first place. Right now, I have to pull the IM off to replace the fuel one due to the common leaky fuel line, so I ordered a new inlet, Grimmspeed phenolic spacers and a AFT MAF hose to do everything at once.

Why do you have to take off the manifold? I pulled my cut harness off while it was in the car.

Just remove the pwr steering, alt, and ac then use wrenches.

And that is supposed to be easier than the 8 bolts holding the manifold? takes like 30 minutes.

There are 3 or 4 hard to get to bolts under the manifold that connect the fuel hard lines and their plastic shielding. Having done it once I wouldn't hesitate to do it again, but its definitely not as simple as the 8 bolts you can see from the top.

Yeah there's 2 each for the harness guide and the fuel rails.

I wouldn't remove the rails without pulling the Mani unless I was wrecking them but the harness can be done

I am aware of those bolts, much easier to do if you pull the manifold, 30 min to get to this state.

At no point did I say that it was "difficult." I was referring to what is quoted above. I said there was more than 8 bolts holding the manifold on, which there are.

[efiniluvr]

If you've pulled the manifold off once, it gets easier everytime. Yes, there are the "easy" bolts, and then there are the bolts that hold the plastic harness rail to the manifold underneath. What I was trying to get at was that, if you need to replace the harness, why not pull the manifold off and do some things (e.g. swap turbo inlet, and the fuel rail if you're encountering the smelly raw fuel issue, which I have) while you're at it.

And to lukeskywrx, isn't that the ver. 8 manifold with the long runners? If it is, you're lucky enough to not have to remove the TGV deletes like most of us

Back to the OP regarding the cut harness, I think your best bet is to switch the WRX harness over, get a AVCS harness, and add/repin according to the DS1 instructions if you're not getting the IA Performance wiring kit.

So here's where I'm at with my swap.
04 wrx
V8 ej207
Jdm ecu
Currently no avcs

Engine starts but idles at ~2100
Engine won't rev past 3000

Unplugging the MAF stalls the engine. Cleaned the MAF because it was nasty, idles smoother but no change.

Could this be due to the JDM ecu and no AVCS?

If you have any ideas while I search through the thread they'd be appreciated.

[lukeskywrx]

No AVCS is going to trigger a bunch of trouble codes, is your CEL on? If so you are pry in safemode.

Also is your IACV OK? they tend to break in shipping so you might want to try your WRX one.

Try your WRX ECU and see if it is better once you check the IACV.

It is the V9 spec-C manifold, same thing as the v8. I don't mind pulling the manifold, I run e85 so I get the delicious raw ethanol smell

Never said anything about easier. It was a PITA when I removed mine and had to clean off the old gasket and then the extra $15 for new gaskets.

Is the mouth of the V8/V9 DP cast iron? It looks rather beefy in the few pics I could find. Also, is the mouth of the DP split to separate exhaust gases and waste-gate flow?

Just curious as to how well subaru designed their DP to help spool

I think stainless, I have one in the garage and Ill snap a pic for ya. Just a big smooth bell mouth.

After some research it does sound like AVCS induced limp mode (CEL is on)

We're working on wiring up the harness now.

Thanks

[D-Rodman]

Sounds like a bad IAC, lack of avcs won't do what you are describing, I'm able to drive my car with avcs disconnected on a v8 ecu, check engine light on from avcs sensors. Put the IAC from your wrx engine in, try it.

But would the IACV keep the motor from revving past 3k?

We're sorting out the AVCS right now anyway. I also swapped over the WRX IAC with a new gasket. I'll update with changes shortly
