Which wires give constant, ignition and ground on a 2006 Chevrolet Impala?

On a 2006 Chevrolet Impala, take constant power from the Red/White wire at the ignition switch harness, ignition from the Pink wire at the ignition switch harness, 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 2006 Chevrolet Impala, the first year of this body.
