The valve you are talking about sounds like the air bypass valve which is used for cold starting.
As for the diagram, do some more searching. They can change from country to country. Another thing if it has come off a leaded vehicle, chances are it never had an o2 sensor.

That picture is of my motor before it went in..
I am not running an o2 sensor, the engine didnt come with an exhaust manifold and i have extractors, im not sure off the top of my head if the 18rgeu ECU uses one.. (anyone ??)

Yes, the 18R-GEU comes with an O2 sensor from the factory. In fact all EFI Toyota engines came with O2 sensors, with the exception of a few engines which were modified for Australian conditions in the early 80's since we didn't have unleaded fuel back then.

Well I did a bit of rooting around at the wreckers and I found out that the Camry that had the 2S-c with a carbie had an Oxygen sensor. it actually had an emission control computer. I looked in the same place on the efi engine and it wasn't there. So I take it that it didn't have one. so I am leaving it off.

The oxygen sensor on the efi models, as far as I have found is on the exhaust manifold, at least it is on the 18rgeu manifold that we've got.

what car did the 2se come in? on my efi 18r-g i used a pre 85 22r computer and harness. the only mod is you half to extend the water temp wire about 6 inches. i used the old 22r stuff because the ecu is real basic, it has no rev limiter, fuel cut off, etc. maybe the 2se is like that also, i have never herd of it.

the cars you are looking for are the RT-142 corona, and the SV-11 camry.. with the 22R-E and 2S-E respectively.

sorry i didnt get back sooner, we have a huge time difference. i used the 81-84 22r-e (celicas in usa) reason being, it is a real basic computer it dosent have a fuel cut or rev limiter. and that is good with the 18r-g's, they rev alot higher than the 22r. the 81-84 22r-e is a 2 plug computer(instead of 3) and dosent have a knock senser. just extend the water temp. gauge wire and thats it. the 22r throttle boby will even bolt to the 18r-g manifold, use 4a-ge blue top injectors, and lean the 22r afm and it will run real good.

firstly, what is the 2C?
Im assuming you are referring to the 2S-E (from an SV-11 Camry).... in which case the loom is not a "bolt in" solution like the 22R-E loom, since the car is comes from is a FWD. That said though, there is nothing stopping you adapting the loom to suit.... although it would be easier to just source the 22R-E loom.
