This is a homemade O2 sim, do you guys think that it'll work (or know if it doesn't?

Possibly. Try it and find out. Not that expensive, if it doesn't you'll just have to buy o2 simms instead. The best way to get rid of rear o2s is to remove them with programming though.

 

No, it doesn't for mine '97. It will work for V6. Tryed it, stupidly before looking at electric system scheme. Actually, connecting two resistors differently you can possibly force it to work, but it was not worth time spended on it and I bought sims. Sims are not just resistors. It is a generator of variable voltage with some short period. I figured this out when by mistake connected A/F gauge to rear HO2 wire
