Easy Installation
You can't beat Sonic Electronix when it comes to car audio! They take great care of their customers! This wiring harness along with the dash kit was absolutely FREE with the purchase of my head unit which was purchased here! At $10 each, thats an instant savings of $20!! without having to do anything! That's the reason ill keep coming back. This kit fit perfectly and worked and looked great along with my new stereo. Came with everything needed to look like a clean, professional installation. Thanks Sonic Electronix!

only cons I have is it should've came with antenna adapter that's the only reason I purchased the radio to keep from spending extra $ for the adapter but overall great product and I will continue to buy from sonic as long as they keep the deals rolling

Clean appearance...
I have a 1997 C2500 which needed minor shaving on the dash plate to fit the top edge of the kit due to using the DIN + EQ face. It looks great and is sturdy. There are other face plate options and hardware so you have choices for your install. ...just confirm your vehicle year and model.

Just plug and play
Installed a new Pioneer stereo in my 1997 Pontiac Bonneville and this product did the trick. Just match the wire colors to those of the provided stereo harness and it will do the job. For my particular car and stereo, there was no need to run a chassis ground, just plug into the harness ground wire.
