Ok so I finally got my car running 4 months later after a big car wreck. S13 w/ rb25. power fc with a holset hx35 turbo. all the goodies to support the power. Car was fully tuned before the wreck.

Now the fun part...... Some wires got cut in the engine bay and I wasnt sure what went to which. So I wired them up to what i thought they would go to. Car started up and ran perfectly fine cruising around. I get on it and as soon as i hit a good amount of boost, my wideband shows a 15+:1 reading.

So i traced the wires back to the ecu and they are:

black/red pin#107
black/white pin#58
red/grey pin#43

Any help would be greatly appreciated!!!!
Thanks

And remember... My car wasnt doing this before the wreck. So Im assuming i wired something wrong.....

or just look up the FSM or pinouts. They are online. Do some freakin research.

107 ground (for the injectors)
58 unswitched 12v
43 start switch

This sounds like a headache I'm in a similar situation with an rb20.
