Bad news....the stock harness wont reach the relocated O2 front sensors even with unhooking them. What now? Some suggest buying a Raptor harness and O2 sensors, but what part numbers, there are 4 different harnesses.
There are people with JBA headers and no O2 sensor extenders. Find where the harness is attached and cut it loose some more. There may be wire-ties in the engine compartment. I will have some hi-rez photos this Saturday to share if I get the chance to install my headers.
