For starters, you should have posted in the R50 section and not the R52 section. That said, the knock sensor is located under the intake manifold, so the correct method would be to remove the upper intake plenum and intake manifold to replace the sensor. That said, many have gone with the relocation method, where they have installed the knock sensor on the top side of the intake manifold where it's more serviceable. I believe they are using a knock sensor and subharness from a 95 Maxima (if I'm not mistaken) and they cut the wires in the main harness going to the original sensor, then splice the wires to the new harness. There are articles that explain the procedure; you might even find one in the R50 section. Or you can Google-search it. Might even be a vid on YouTube showing the procedure.
