Description:

Easy to install: Without cutting any OE wire harness.
Compatible Models: for 2002-2008 GM Chevy Silverado Impala GMC Sierra Buick Cadillac.
NOTE: car stereo radio wiring harness is not compatible with amp systems like for Bo-se, for In-finity, etc.; not for 2006 Silverado LT, NOT FOR 2004 Chevrolet express van, NOT FOR 2005 Sierra 1500.
Function: wiring is not for all models, but if the OE radio harness of your vehicle does not have an ignition wire, the aftermarket stereo cannot be turned off/on through the OE radio harness; To solve this problem, you need to get a 12 v power supply from the ignition by running the red cable separately from the factory radio harness.
