Need help on some wiring.

Hi,

I'm swapping a 1UZ-FE into my GZ20 soarer. I'm almost done with the harness, but i'm missing some wires on the ECU diagrams.

I have used these diagrams to figure out my harness:

http://www.lextreme.com/pdf/scecu2.pdf


But my harness is a little different.
- My engine lacks the 4 heated oxygine sensors, and has only 2 single wire sensors.
- There is no TRAC on the harness
- No feul pressure solenoid
- No EGR
- No sub throttle position sensor
- I'm not gonna use the Hydrofan any more
- I'm ditching the A/C

And i have a couple of wires on the ECU that are not noted in the wiring diagrams.
These are the wires on the 40 pin connector:
Pin 25 - red/white
Pin 26 - red
Pin 27 - pink/green
Pin 29 - yellob/black
Pin 30 - lightgreen/black

They all lead to a white dashboard connector, and i have no clue what there function is


I hope someone can tell me if i need these wires, or just to ditch them.


Oh, and does anyone know if there are is someone selling engine mounts to fit the 1UZ-FE into a soarer/MKIII supra (subframes are the same)

Thanks in advance,

25 26 and 27 are not needed

think they are for air suspension or some sort of communication with another ecu

29 and 30 are for the cat converter over temp sensor and warning light

how many pins are on the oxy sensor plugs for best results and fuel economy try get
the matching sensors this way if u ever have probs down the track u dont have to change plugs from factory

Thanks for the help on the wires!

About the cat converter over temp sensor; will the ECU miss this signal and show a warning? Since i'm not planning on using a catalyst, nor the temp sensor

The oxy sensors are single wire. They where not removed when they shipped the engine to me, so i should be fine with that.
