Hey Guys, i currently have an AutoCal from Justin@Blackbear, and since i went turbo im going to switch over to SD, but i need to wire my Widebands 5V output into the ECM using some unused pin, so that it can be data logged and Justin can make my tune.

In NBS i see people have done it through the EGR.
In Corvettes Ive also seen people did it through the A/C pressure sensor, with a switch i think...

I have an 07 NNBS (4.8) with the E38 ECM, can anyone guide me?

OR, does anyone have a Pinout?


Thanks!
