Which wires give constant, ignition and ground on a 2014 Nissan Frontier?
On a 2014 Nissan Frontier, take constant power from the Green wire at the ignition switch, white 6-pin plug, pin 3, ignition from the White/Green 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 2014 Nissan Frontier.
This truck has a standard key. Many of the body wires on this page come from Nissan's own service manual, not just installer sheets, carried to 2014. Our own team has not yet metered these on a 2014 truck.
