The Corolla harness has 3 plugs on the fusebox end and none of them match the yaris. You must move every single wire to its corresponding location in the yaris' CA1 and CA2 plugs.(I'm almost done). In addition to re-pinning, you will also have to cut the 2zr harness battery cables going to the starter/alternator and connect them to your 1nz harness cables for the extra length and the proper ends....lots of work.

NOTE: You can see my mini add-a-circuit for the MAF here

Is there also a difference because your car is an automatic? (ie: are there additional wiring and harness implications because of the automatic?)

I understand what your saying but can I suggest a bit of rewording... Try to do a step by step process in 1 post for the wiring with what you have acquired (yaris harness and yaris Trans).
-Then have a separate post if you use the yaris harness with xD trans,
-another post for yaris trans with the xD harness,
-and another post for the xD harness and xD trans.

After that is done, if you could go ahead and mention corolla parts.

You are mixing scenario's up in 2 different posts and I can see how this can get confusing and intimidating for someone who is a newbie with wiring. I used to work for Toyota and Lexus for 6 years, so its a bit easier for me to understand.

Great job though. looks fun, I can't wait to do this to mine! I have been talking about doing this for a LOOONG time when I found out that the 2zr was the Yaris TS version.

Im sorry for the confusion, but I mention the Corolla harness because thats what I'm using on my 2zr/yaris trans buid. I wanted to test ALL of the Corolla parts so no one else would have to. I want this to be easy for everyone, so again just to be clear........aside from the actual engine and accesories, USE EVERY PART FROM A SCION XD.

I know you guys would prefer this diy be formatted a certain way, but I am sharing this info with you guys as I go.

You're doing great. Keep it up! Whenever I do something worth sharing, I always find it difficult to document until after it's done. The effort is appreciated.

Cheers.

This is exactly how I felt about this diy, there is so much going on I feared a step would get forgotten if I waited until it was completed.

You're doing great! Worthy of many accolades for doing and sharing with the rest of us this engine swap.

Would you mind posting the part # of the ECM you bought, and what it was for?(ie year make model and specific options)

fredovvti · 01-21-2016, 07:07 AM

If I get a complete xD harness and use the Yaris trans, I only have to move the pins that you mention in post #48 to the correct location of the plugs ends and that its?

ArmstrongRacing · 01-21-2016, 12:11 PM

There is no additional wiring involved in having an automatic vs manual transmission. If your car is auto and you keep it auto, the auto trans Xd harness and ECM have the same pin locations at the transmission plugs. There is only one wire to ground, Ill get to that later

Where I'm coming from is 2010 Yaris 5spd manual without ABS

So, just like some of the others, as I read through your helpful posts.....I try to harvest the info for my own situation (ie: which mounts / tranny / axles / wiring etc...)

I finished all of my Corolla harness soldering today. I connected the battery and switched on the ignition and I immediately got a code for P2770-Torque Converter Clutch(auto trans).....Im not sure if this is a result of the hydrolock or what, looks like I need to do a bit more research...

Tomorrow I will finish my MAF wiring and fire it up...hopefully all goes well.

So far, it was just four wires you had to change? (pending figuring out the P2770 code of course)

For the Xd manual trans harness yes, 4 wires so far.

Update: (auto trans only) I've found the harness discrepancy causing my P2770 code. The Xd ECM normally receives a signal from the SL solenoid on pin#58, but my Corolla harness has that wire on 57. Also the Corolla/Xd valve body's ground this solenoid internally vs the Yaris auto trans grounding this solenoid at the ECM. I just need to swap pins 57 to 58 and ground pin #9 at the valve body connector.

How did the wiring go for the corrolla harness to XD/yaris? Any left over wires, or were you able to terminate/find a place for all the wires? Just wondering how viable using a corrolla harness is.

maralieus · 01-22-2016, 02:20 PM

So what did you need for cali smog? You just had to call ahead and tell them your plans and that's it? Then just make sure it has no check engine, cat, and that's about it? I'm very interested in doing this swap as my yaris tranny is getting iffy and the engine has 150k so it is in the cards.

ArmstrongRacing · 01-22-2016, 02:36 PM

Yes I called the BAR and they said no CEL, and all stock components.

ArmstrongRacing · 01-23-2016, 04:16 PM

This is the ECM I ordered from Ebay...I just have to finish up some wiring and Ill have a engine startup video.

Bluevitz-rs · 01-24-2016, 08:36 AM

what's the engine immobilizer situation and how are you addressing it?
