Hey all, I have a 2017 Silverado 5.3l that's turbocharged, has BTR cams w/ 32% fuel lobe, and springs/rockers. I had some issues not related directly to this, so the car sat parked for a while. The last few days I've been digging in an rectifying all the small things. Pulled the o2's and they were all fouled; thought it was best to go ahead and replace them. However, the second "after cat" o2 sensor harness had to be elongated for us to install the turbo setup. The harness is 49 inches. Does anyone know of any oem 4 pin o2 sensors with a longer harness that would work? We spliced and electrical taped last time, but the tuner did note that one o2 sensor wasn't reading and was at a constant 5v, and looking at all of them, my guess is it was that one. Id prefer to not elongate again if I dont have to. (pics of the truck fo' fun)
