On the plastic box, there is an output for the heads up display for the AFR, an input for the o2 sensor, and one more is one input/output that I do not understand. It is next to the input for the NTK o2 sensor I have. It is a white cable with 6 wires (black, brown, orange, blue, white and green). Where do I connect this? and what is its function?

 

No 100% sure about this question. But in your other thread, I would leave the stock sensor in and run the WB separately.

You can turn off 02 Feedback in the PFC and not use the stock sensor. I like to leave it on for cruise conditions. You can watch the 02 readings bounce from 14.0:1 to about 15:0-1 which is pretty neat. As soon as you tip in on the throttle a bit more it defaults the tuned values in the 20x20 map.

 

Where should I get the bung welded for the NTK sensor if I leave the stock sensor in?

 

..... anyone?

 

I'm not sure how susceptible the NTK sensor is to heat, but with the Bosch on the LM1 I mount it about a foot behind the turbo.

You should be able to find a bug nut and bolt at any muffler shop.
