I'm looking for information on the 2015ish factory wideband. I'm pretty sure they are bosch 4.9. I would like to wire it up to work on my emu black. I can identify the heater wires no problem. The factory wiring schematic does a terrible job explaining the remain three wires. Any help would be a great appreciation.
I have found this link helpful with understanding different Bosch LSU sensor wiring:

Be sure to look around at other pages on that website.
Thank you very much! The ford sensor i had could not have been a wideband. I ordered the proper 4.9 and wiring is spot on!
