27th of May 2012 – The JDM A/T wire colors are correct – checked them from my harness.
22-03-2015 EDIT: control wires for A/T gearbox (L1,L2,L3) might have been in different order. I made a error at some point
10P connector:
E01 | Ground (Engine ground Power) |
RSC | Idle speed control – closing coil |
STA | Engine cranking signal (starter switch) – circuit opening relay |
EGR | Exhaust gas recirculation vacuum switching valve |
NSW | Neutral start switch |
E02 | Ground (Engine ground Power) |
RSO | Idle speed control – opening coil |
IGT | Ignition timing – ignitor primary trigger |

Hey man, just discovered your site, I also have a 4A-GZE converted to turbo, but in a… Yaris 😀 I’m currently cleaning it all up and will re-do the electronics with a standalone ECU, so I think I can learn a lot of things from you 😀
Anyway if you wanna know about my crazy machine: https://www.facebook.com/etimagosgarage/
Sounds good! I’m fairly sure it is going to be crowded under that Yaris bonnet.
If I can give some advice, don’t do things like me. Plan ahead and stay away from quick hacks. I’ll have to redo plenty of stuff.
I’m sorry, I’m not a Facebook user.
Oh yeah, it’s really shoehorned… The reason for going turbo is that the SC intake manifold was just a little too deep. And the workshop had to shorten the runners on the NA manifold, not to mention notch the frame rails!
Taking my time now, been dismantling the car for the past 3-4 months, so I can rebuild it better, stronger and faster! And learn along the way, I never did this kind of thing before!
Here’s some pics from Google photos: https://photos.app.goo.gl/2kL9RPtNNhbgpTHF7
Wow, that sounds like its done properly! I think I need either to shorten the manifold too or get a custom one, because currently it is hitting the engine bay locking latch. Notching frame rails would not fly here because legal issues. :/
Neither have I done anything like this before. Doing and learning.
I’ll check your photos 🙂
Yo searock are you in Australia? I want to pick your brain
No, sorry, I’m in Finland – but when you come to pick my brain, bring some beer here 😀
Yeh great build man very impressed the more I look the more u have covered that I wanted to ask
You know, Ive never heard someone use that “pick someones brain” my sis told me what it meant 😀
