I have a 90 240 wagon with 195,000

I need to replace the O2 sensor and am not sure which one is correct.

Mine is located in the cat( 36") and has three wires going to it ,
one black and two white

I'm looking at the sensors that FCP sells and figure I need the direct fit
3 wire universal but it also looks like there is another that would work
that is listed.
Which of these is correct:

•Direct Fit Oxygen Sensor fits all 89-92 models and 93 non California Models -----$135.00 Bosch

•250-2300 Universal 3 Wire Oxygen Sensor fits all 85-92 and 1993 non California Models --------$49.95 Walker

Thanks for the info
