Oxygen sensor 4 wire square white/gray gen 3 (242, E40)

APPLICATION: Gen 3 LS/Vortec drive by wire engines.

PARTS INCLUDED: Single oxygen sensor

NOTES: Oxygen Sensors are one of the most important parts of an LSX Swap. They relay the Air Fuel Ratio back to the ECM so your engine runs Optimally. O2 Sensors are a Wear Item, just like a spark plug or serpentine belt. O2 Sensors that are high mileage, have been submerged in water, have been removed from a junkyard with a torch, or are in any other way damaged, should be replaced. PSI Wiring Harnesses are Designed to use a Specific O2 Sensor, usually based on engine generation, HAR-1014, HAR-1015, HAR-1094, HAR-1095.

    • Part and customer service
      Bought part 4-5 years ago prepping to swap 5.3 into 1960 C10. Swap took quite awhile. When we got to exhaust system, we found sensors and harnesses had male plugs. I figured I ordered wrong part and after 5 years, I'd have to eat it. CS rep was able to find the order( thankfully I had still had the packing slip). He determined that the wrong sensors were shipped. I had the right sensors in my hand 3 days later. Totally, professional and righted a wrong instead of making excuses. Harness was installed and vehicle runs great. If I ever swap another LS, PSI is first place I'm calling.

    • Don’t forget these!
      I purchased a harness and forgot to get compatible O2 sensors. Ended up coming back and ordering these. Work great!

    • Surprises
      I like my harness. I just don't like surprises. I ordered my harness and gave specs to salesman . Drive by Wire was one of these, however when it came time to plug and play I had to wait on additional harness for throttle body. SURPRISE!

      The fan harnesses are great, I wouldn't have known about it if a friend of mine asked if I also bought fan harnesses.
      All in all now that I have it almost complete, I would get another PSI harness.
      Shout out to GARY !
