wire harness from Courtsey Nissan & a Nissan Knock Sensor from RockAuto.com. To get the knock sensor I got one from a 1999 Nissan Maxima for $69.00 (genuine Nissan package). You will need a bolt too so go get a M6-1.0 x 30mm and two washers. You may need some wire heat shrink and some electrical tape.. On the knock sensor relocation, I'd recommend you do some research on it before you make the move. Depending on what your long-term plans for the vehicle are, a knock sensor mounted on the intake is useless for detecting engine knock.
Use the copper wire to connect the positive and negative terminals of the knock sensor. Using the 2004 Nissan Frontier Service Manual, look up the exact specifications of your particular make/model of the car and locate the diagrams that illustrate where the wires should be connected..
