Hey guys, so a buddy of mine drives a Pontiac G5 2009. The one with the basic model stereo and no onstar either.
He picked up a Kenwood double din that he wants to install.
I read that I may need one of these for his car:
CAR RADIO/STEREO WIRE HARNESS INSTALL INTERFACE ~ AXXESS LC-GMRC-LAN-03 | eBay
Or can I just get by using a basic harness like this?
New Car Stereo Audio Dash Wiring Harness Wire For Installing a Aftermarket Radio | eBay
I don't really care about the chimes and turning signal noises, and I can run the accessory wire to the fuse box. Would it be okay or would it affect anything else?
