the wiring is simple. a four wire sensor has a power, signal and two grounds. one is heater ground and the other is shield. I wired the grounds to the kick panel next to the fuse box. I'm using the key on power from the rear window defrost spot (unused in this truck) and the signal runs up to the original sensor plug in the driver inner fender. i show this plug in the video. hope that helps. thank you for watching.
Had a question about the 4 wire o2 upgrade. Im trying to figure out where i can ground the other two black wires and dont wanna use 20 feet of wire. Where did you ground the two black wires?
Would care to see how you wired the O2 sensor and where each wire for the 4 wire conversion went. Awesome content!

@@SnaleRacing did you just crimp it in with a fuse or had fuse to wire set up?
@@itsgatormane i actually jumped it off the unused rear window defrost fuse hole. but an inline would do it as well.
looking good!
thanks!!
Great tip on cleaning the injectors.
Changing from a single wire sensor to a 4 wire sensor, does the system still read it correctly?
yes. all regular O2 sensors read 0-1V. later AFR sensors use a 5V or 12V reference. to read a wider range, thus wideband sensor.

Basically anywhere to the body. i grounded near the fuse box at the driver A pillar.
