Vehicle-Specific Integration Harness

The Axxess AXBUCS-NI406V is a pre-wired AXSWC harness designed for the Nissan Maxima without factory amplifier from 2016 onward. It enables installation of an aftermarket radio while keeping the original auxiliary input jack and backup camera functional. The kit includes the AXCSD-6V converter that steps 12-volt power down to 6 volts for the camera.

Replaces Direct Splicing and Adapter Stacks

This harness eliminates the need to cut the factory wiring or chain multiple adapters together. The jump is worth it when you want a plug-in connection that preserves both the AUX-IN port and the rear-view camera without custom fabrication. It is not for vehicles equipped with the factory amplified audio system or for owners who prefer to solder each circuit individually.

Limited to the AXSWC Steering-Wheel Interface

The pre-wired leads only carry the signals required by the AXSWC module, which is sold separately. Without that module, steering-wheel audio controls will not communicate with the new radio. The 12-to-6-volt converter is calibrated for the factory camera alone and cannot power additional accessories.

Questions about this item

What connector does the AXBUCS-NI406V need to reach the factory AUX-IN jack on a 2016-up Maxima?

It uses the vehicle's original AUX-IN jack wiring; the harness plugs into the factory radio connector behind the dash to keep that jack working with an aftermarket stereo.

Which step do installers often miss when fitting the AXCSD-6V converter included with this harness?

The 12-volt to 6-volt converter must be powered from a switched 12 V source so the backup camera only receives voltage when the ignition is on; skipping this leaves the camera powered constantly.

What part will need replacement if the factory backup camera feed stops displaying on the aftermarket radio years later?

The camera itself or its coaxial video cable are the typical failure points; the harness and included converter are passive and rarely wear out.
