Default Mystery connector on ef/b18b swap

I have a 2-pin connector on my driver's side coming off the injector harness. It looks like the previous owner has spliced it in and I can't figure out what it is. The connector has a red/yellow wire and a green/white wire going to one blue/yellow wire.

I've been trying to figure it out on several wiring diagrams w/o any luck. The previous owner had the same motor in the car except the harness was all hacked up for a mpfi conv. and obd0 b18a swap. I've gotten most of it straightened out except this one connector. I'm hoping if I can find out where it goes it might solve my code 43 issues

thanks for any help and sorry for the drawn out explanation

that would be a green connector with 4 red wires and since I have obd2 injectors I have no need for a resistor pack. The wires were cut, soldered together and neatly tucked away.

But the plug was obviously spliced into only one wire by the previous owner. The only blue/yellow wire I can find in an ecu wire/function chart is for the EACV

EACV=IACV. You'll need to find the black/yellow wire for the IACV/EACV and wire that back up to the sensor plug. I believe the bottom wire is the black/yellow and the top is blue yellow. The black/yellow should be switched 12V. So on your plug it should be black/yellow=red/yellow, blue/yellow=green/white

then that brings up another question: what the hell is the 2 pin green connector I currently have plugged into my IACV?

Thanks for the help by the way

the wires on the harness are light blue and blue. the wires on the connector are blu/yel and black yellow. I don't have a code 14 right now but when I unplug the connector on the IACV then I get a code 14
