96 engine harness into 98?

[vinhisbored]

my car's 98.. and some plugs are messed up.. so i thought it'd be nice to just buy a cleaner harness and throw it on. another member on here has one from a 96.. would it fit/work with no problems?

also wondering about 02 sensor.. could i use any 95-98 02 sensor on my car? or would i have to use a 97-98 only?

Im not sure about the harness. For the front O2 sensor the 95 uses a 1 wire while 96+ used a 3 wire.

The 96 uses a 3wire rear O2 sensor while the 97-98 is 4wire, so the plug going into the lower harness is different.

Also, there's 2 pins at the ECU that are different on the 96 harness vs. 97-98.

The front O2 sensor is the same from 96-98.

Finally, the wiper motor and wiper amplifier plugs are different on 97-98 models.
