Oreillys Auto parts carries BWD (Borg Warner dist.) Knock sensor for half the price of the Nissan brand. now here is the catch, once you open the box, the sensor is a JECS made in japan with the Nissan stamp on it.
As far as the harness, they sell the pigtail for $5 which you can splice/solder into the gray oval plug.
Also the injector harness/plug off of most VOLVO's will plug into the knock sensor and injectors, and and the difference is the Nissan plug uses a silly U shaped annoying clip, vs. the Volvo ( which is essentially a common BOSCH style) style plug has a U shaped clip however it has a push/squeeze type clip, thus is easy to plug/unplug most square Nissan harness's.
i just picked up a knock sensor from Oreillys and a Volvo BOSCH style harness which i will use for my relocation of the sensor. cost $50. harness free from my previous Volvo.
