Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

Sonic Electronix Store
Pre-terminated wires give me less to worry about, i.e. do I have the right size connectors and do I have enough of them. Also saves time.

I'm assuming this doesn't integrate any of the chimes/warning sounds and whatnot?I have a 2001 Chevy Malibu and need a harness that retains all the original functionality. Would this be what I need?

Best Answer: Hi Bob,

GM makes their vehicle rather convoluted when it comes to their 'original functionality', so you may need to elaborate or give our sales team a call to make sure everything is covered(!). Nevertheless, below are the three most likely module that you seek.
