I freggin broke mine so I found one from 93 626 but it has 4-wire, also I have one from 89 626 with one wire like the Rx7 just need cut wire & reuse mine to make it plug & play. or I need to get Rx7 specfic made Rx7 o2 sensor?

dont you have a power FC?

yes

626 one should work ok, might not last as long

if you have the power FC, then just disconnect and forget about it.

It's a 1 wire sensor. You can pick them up at any auto parts store for around $20

Thanks guysw basically I was trying to determine what is the major difference between o2 sensor, it look like they all pretty much do the same thing.
