Which wires give constant, ignition and ground on a 2021 Nissan NV 1500 / 2500 / 3500?

On a 2021 Nissan NV 1500 / 2500 / 3500, take constant power from the Green wire at the ignition switch, white 6-pin plug, pin 3, ignition from the Blue wire at the ignition switch, white 6-pin plug, pin 1, and ground to clean, bare body metal. Meter every wire first.

Written by API Signal, fleet GPS and camera installers for 35+ years across Georgia, South Carolina and North Carolina, installing every major telematics and camera brand. Every wire on this page lists its source.

Test every wire with a meter before you tap it

No wiring information is ever guaranteed. Colors and locations change with trim, options and build date, and the manufacturer can change them in the middle of a model year. We share this as a starting point for installers, and you are responsible for confirming every connection on the truck in front of you.

This page covers the 2021 Nissan NV1500, NV2500 and NV3500 full-size van, the last year.

This van has a standard key. We found no Nissan service manual for this year, so the colors are carried from the 2012 to 2016 manuals. No wire source names 2021 at all. Meter every wire. Our own team has not yet metered these on a 2021 van.
