Well, I'm just not 100% sure about this. I wish I had a description of the wires. Here is the deal...Firt pic is the install sheet for the IS300 ECU. The second pic is our ecu.

There is a power and ground wire. There is 2 wires in and 2 wires out (red/black and yellow/black)...putting this device inline with the 2 tranny control wires. The "X" marks are where connections. Any thoughts if that is the light green and dark green wires?

 

On the ECU data sheet from Greddy, those 2 connections are not defined. I presume because Greddy has no use for them. But does anyone have a description of what those 2 wires are (light green and dark green wires- 2nd connector from right)?

 

Best bet is to probably call Scion and ask.

 

Maybe engifineer knows? By the way can I just buy the is300 kit and it will work? I assume thats what youre doing? coolness!!!

 

i cant find what those wires do from ecu pinout that enginfineer sent me. they are pins E7-34 and E7-36.

 

Isn't that weird. Those 2 wires are there...but no description of what they are.

 

bump

 

try searching online for a EWD for the tC or calling up the dealer to see if they can get you one; it will detail all the wiring in the car, including the ECU

 

Pin 34 is the Ground for the Transmission Revolution Sensor.

Looking up 36.

 

How GREAT can JMiller be?

He is THE MAN

Looks like it for sure is for the tranny. If the other one comes back right...I'm installing tonight!

 

I assum you went through the ECU pages in the tech section on SL, in teh repair manual ?

 

Ok got it.

Pin 34 (Green) is for the (-) side of the Transmission Revolution Sensor (Counter Gear).
Pin 35 (Light Green) is for the (-) side of the Transmission Revolution Sensor (Turbine).

 

Maybe but it wasn't on SL. It's from the Wiring Diagrams.

 

I went thru everything I had access to....until later

No descriptions for those 2 wires on all the ECU information I've found...even from Greddy for their emanage. Probably because they have no need to deal with it.

 

WOW.....That is PERFECT. I own you BIG TIME

 

you just got owned jmiller

 

Ummmm....I OWE you .

 

No sweat man, glad to be of some help.

 

Well, to be on the safe side (didn't want to blow the sensors) I called Turboeast this morning and asked if this was correct to hook into.

They said NO

It appears everything is the same electronic wise between the IS300 and the TC, but they moved a few connections. They will email me their installation for the TC this afternoon.

Man oh man am I glad I waited.

 

so lets get some results! =]
