ok i've been pouring over some past entries and looked over techedge's website as well, and i still can't seem to figure out where the simulated narrowband output goes to. i understand how everything else works and hooks up. i would assume it either goes to the ecu or stock o2 connector in the engine bay but i havent seen any documentation on it. one connector obviously connects to the sensor itself. theres a 9 pin port that is for the display or other dataloggin stuff, and theres two wires to power and ground the unit right? am i missing something?

if i understand correctly the 1.5 should be the one that allows u to replace ur stock o2 with the wideband so that you dont have to simultaneously run both and eliminates the need to weld in another o2 bung as well right? just curious as to where the narrowband output supposed to plug to and which wire it is on the unit itself. thanks for helping out this confused fool
