I'm wondering if anyone here has ever purchased an o2 sensor that needed to be wired and if wiring it was any difficult.

I'm having some issues with my downstream sensor and AutoZone has them wired for like $200 so I'm thinking of buying an unwired one which is a little less pricey.

 

It's easy but it won't last. The connections corrode over time. Go on rockauto.com and buy a prewired one.

 

Which 2 do we need? there is alot of different ones on there

 

Are these 2 it?

What code are you getting? If its the P0421 you might wanna search around on here. It's what I'm going through right now.
