It's in the trunk behind the carpet motor side.

You are talking about the SW20 MR2's correct? If not, then I don't really know.

Welcome, and sorry for not seeing the second question. My father is a Toyota mechanic so I had him printout the schim. on the wiring. But that was for my Air/Fuel meter which I believe I still went wrong somewhere in the wiring. If you can just run to the nearest Toyota dealer and ask them for print them out for you, hell you can probably find them online if you look hard enough.

Did you figure it out?? Apexi has the installation instructions on thier website (also a printed copy should have come with your SAFC).

Hehehe, Yeah I think you're suppose to run the wires from the ECU to the front of your car to mount it. No point having it in the trunk if you can't see it. Glad to hear you got it working though.

i used to have it setup in my eclipse.... i really have no need for the display im putting my car on the dyno and will have one of the guys tune the car from the trunk.... after that i really have no need to look at the safc i def don't mess with it after its in the car... i also figured there is no point n running it to the cabin because im hoping this summer to have an ems put on neway... i just had the safc 2 sittin around after i wrecked my eclipse so i decided to put it on..... lol it all i fine all i need is the correction i have no need to tune it after that

heh, trunk mounted stuff.... can't say much, i have a boost gauge and voltmeter mounted in the trunk (mainly because i got them and the holder for a whopping total of $7)... neverfear, i have an electronic autometer boost gauge on the way

um, for the a/f ratio gauge you just need the sending signal wire of the o2 sensor connected.... but those gauges are more of a lightshow than anything helpful
