Don't replace the factory narrow band with the simulated signal, trust me it doesn't ever end up running properly
because it doesn't "switch" back and forth like a real narrowband. My afrs keept sweeping strangely and the ecu didn't seem to happy. You can however either weld in an extra bung for the wideband and leave the stock narrowbands in place, or put a complete simulator to replace the back o2 and put the wideband in its place. I think I have an extra o2 simulator if you want one, that way you don't need an extra bung welded in.
Btw the UEGO is a good piece.
