Adam , 95 is different than 92-94 and 96-97. I fugue his car is 92-94 so that should work for him.

yeah Mark's engine is supposedly from a 1991 (hopefully the same as 1992 sc300) and his car is a 1992 sc400.

but adam, what i was saying was totally different was the sc400 stuff. i see nothing on the sc400 diagram that shows the injectors being powered by IJ1 pins 3, 7.
power just goes from IGNITION MAIN RELAY, to EB2 PIN 2, then branches out to all 8 injectors.

i am painfully confused now.

Note the power flow: Power comes in at (top left) "a" B-O wire. I neglected to post all the way to the source, but this power comes straight from the 30A AM2 fuse via the ignition switch. This single feed branches off to feed both ignition circuits on the SC4, as well as passing through to feed the injectors. (middle right)







See power for injectors come in (lower left).

Note: The injectors and ignition do not power through the main EFI relay. The main EFI relay feeds the IACV, O2, fuel pump, and possibly other sensors on the JDM engine. On the USDM stuff, it also feeds the EVAP and various smog related VSVs.

I know it seems we have a few versions kicking around, but the more I look at it, the more I think it may just be slightly different presentation of the same data, ie. Aldata is calling the ignition switch the "main ignition relay".

All these diagrams worked perfect on my 92.
