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

 

anybody?

 

pics would help

 

I'll try to get one up today

 

Does this help any?

 

Intake Air Temperature sensor.

 

nope thats on the other side of the car actually inside the intake

 

resistor pack for the peak and hold injectors?

 

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.

 

iat is green white, red yellow
iacv is blue yellow, yellow black


Here are the only plugs on that side that I know of that look like that and their colors.

 

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

 

what color are the wires?

 

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

 

anyone else?
