Going SBEC and 4 wire O2 sensor on the CSX. Normally I would just buy the right one listed for the 89-95 cars and call it done. NTK 23023 for 2.2
But the problem of obsolescence and not being able to get the matching harness half of the connector shell is a slight stumbling point.
I would rather buy something newer and have the ability to have a matching plug shell TE 184246-1 and have an off the shelf readily available part. NTK 23159 for SRT-4 With the added bonus it is slightly less cost
Other than the connector plug and possibly wire length are those two sensors even different in function and output signal ? I cant see chrysler reinventing the wheel on something like that but who knows.
