I just swaped my motor today but I could put the o2 sensor. I used the o2 sensor from my stock 94 CX and tried to plug it to the 95 LS wirirng but the LS wiring has 2 wires and the CX o2 sensor has four wires so the plugs are different. Any help would be greatly apreciated, Thanks alot

 

the 4 wire is a heated o2 the 2 wire is a standard o2 sensor... go to Autozone or the like they'll have universal one for cheap I'm sure.

good luck
