While this is advertised as Plug-n-Play, it’s really not. You have to run some extra shielded wires for two signals as it does not come with with the crank and cam signal wires. This has happened to about 4 maxima owners who purchased this harness. Overall, the harness does work but it’s not straight plug-n-play and questionable if its worth $500. Car may or may not run without these wires so please keep this in mind.
