Default Wire colors in 1.6L AFM harness for IAT splice

I've been searching but doing this on the phone sucks.

Does anyone know the color of the two wires in the harness going to the AFM that you need to splice into with the two wires from the GM AIT. I want to do it fairly far back to avoid complications when I have to pull it out and get the car smogged

splice?

I know it's very unnatural, but shove your male wires into the female connector itself.

He did mention wanting to do it as far back in the harness as possible to sneak it through emissions.

ground- black
2O- red
2P- red/green

Based on the MS instructions they say to connect pins 1&6 to the GM IAT.

There are 7 connectors on the AFM plug and if I'm reading the wiring diagram it looks like I'd need to connect to Black (1) and Red (6)?

I also noticed that there is what looks like a switch between Black (ground) and Light Green for the fuel pump. Is that going to cause problem if the plug is not connected to the AFM?

One side of the IAT will always go to ground. The other needs to go to 2O or 2P depending on how your boomslang is wired. I think most builders use 2O, so yea that would be the black and red, 1 and 6.

Fuel pump switch. Yes, youll need to jumper or tie the light green wire into whatever pin on the boomslang harness connector that is controlling your FP. I just connected that to pin to 2P in my boomslang and jumpered it at the AFM conn.

thsi is my wiring diagram I made for my car, notice the bottom right corner area
