multiple ECU errors 95 Max - 033, 034, 053, 077 - is it the harness?

ECU codes 33, 34, 53, 77 HELP!
Originally I was getting intermittent O2 codes that would go away when I cleaned each respective connector under the hood and reset the ECU. Now, no matter what I do I still get all 3 O2 sensors failed and the knock sensor. I read somewhere there is a harness problem with a TSB from nissan that deals with this issue. I can't find it or any details now. Does anyone have experience with this?
If it's wiring I'd like to know before I replace $350 worth of parts that I may not need.
Thanks
Paul
