I am currently replacing my PHH and heater control valve, and figured I would look into my No. 2 knock sensor (CEL 55) while I'm working in that area. I've had the cruiser for a little over a year, code 55 was present when I bought the truck. I haven't looked into it until now because I was not experiencing any major runnability issues. I've replaced the front No. 1 knock sensor with an OEM already.
The No. 2 knock sensor is not present on the truck, and there appears to be some sort of plug or aftermarket sensor in its place. It also looks like the engine wiring harness has been modified as well, as the electrical connector definitely would not mate up with an OEM sensor.
Any suggestions on getting an OEM sensor back in its place? Just keep driving? Removing and replacing the sensor seems like it would be easy enough, but I'm worried about messing with the wiring around engine harness. Any pointers would be greatly appreciated, and I've thrown a couple pictures down below for reference.
