I hooked them up! but only the one on the drivers side works :/ The passenger one pops my fuse :/ the wire underneath is cut so its shorting out..... also nothing on my harness fits this one, it is the front o2
So to put my wideband on would i put it in the passenger side? The one that doesn't work?

Front or rear O2?
Different years used different connectors on the front O2s.

That connector looks like a 1999 or 2000 oxygen sensor.

Its the font o2 and yeah you're right its a 2000 But my harness is a 2002

Once i get my wideband would i turn all of the other ones off?
Do i just take out that o2 on the picture and put the wideband there?

You want to keep your front o2s if your planning to run your truck in Closed loop. Check this link out. Very informative on the wiring. Iknow it says LT1 but, its mainly LS stuff

How are you goin to tune it?
Im speed density open loop so i have no use for any of the oxygen sensors nor MAF.
If your goin closed loop, then yes you need them. Weld in an extra bung on either bank for your wideband and your good to go.

Welll.... not sure yet actually, I have EFI live and i wanna speed density but i just haven't learned yet. So i wanna say closed loop for now.
If i go speed density I wouldn't need a wideband?

I would recommend you stay in closed loop... If you go speed density then you would need a wideband for tuning purposes. You could probably tune it without one, but it makes tuning alot easier and more accurate/safer to use one.

Regardless of closed loop or open loop, I would recommend a wide band. You will require one for open loop. Keep your front o2s and weld a separate bung in for the wide band.

I plan on getting a wideband soon before i start doing my own tuning


Yeah ill weld the bung where both pipes collect
