Which wires give constant, ignition and ground on a 2023 Nissan Frontier?
On a 2023 Nissan Frontier, take constant power from the White wire at the BCM white 15-pin plug, ignition from the Lavender/Brown wire at the BCM black 40-pin plug, and ground to clean, bare body metal. Meter every wire first.
Meter every wire before you tap it. Colors change with trim and build date.
