I bought an adapter that ended up being incorrect so I'll take the one pigtail off and hardwire it in. That way the sensors can still be changed. It kills me because the sensors were expensive and are correct for the donor vehicle.Yeller wrote: ↑Fri Feb 10, 2023 11:41 am O2 sensors are a pain….. never understood why they have so many different connectors for a 4 wire sensor.
I know they are expensive…. I would buy the correct O2 for the harness. But to be clear are you looking to change the plug to the plug for your sensors are are you looking to eliminate the connector all together? With O2’s being a disposable part I would want a connector.
I own one swap that the O2’s do not read, the ecm sees them but they just flat line and could not figure out why. Was having that engine dyno tuned anyway for other issues that were known prior to the swap. they cleaned up the fuel maps and it runs great from sea level to 14,000 feet.
