Hi

The C5 Corvette I have came with a Jap import style double din bag of crap from the 90s, which I’m now trying to swap for a JVC single din. Had hoped this was plug and play as I’ve not touched car audio for about 10 years but no such joy. Hopefully there’s an adaptor or harness pre wired that’s available, but here’s what I’m currently looking at.

This is the wire that is currently in the car that came from the Jap stereo:

21150


This is the wire that was loose in the car so guessing the standard Chevy one:

21151


These are the two ends of the harness that came with the new JVC headunit:

21152
21153


Aaand this is the back of the JVC unit:

21154


Any help appreciated!

Would need to know the year corvette and all i do is type the year and make car wire harness on eBay or Amazon and it'll show you the right harness...actually will show you 10 different ones to choose from but all the same.

Hi, yes thanks I did try that. It’s a 1999, all the wiring harnesses I see have the big boxy end like the one supplied with my headunit, which doesnt currently exist in the car. Like I say it isn’t going from the Chevy unit to aftermarket, it’s going from an older aftermarket unit to a newer one. I’ve chased the existing harness back as far as I can physically see and there doesn’t seem to be an additional plug.

You will need to splice a harness (Metra, Scoshe) to the HU harness. Also will need a GM antenna adapter. the harness from old HU may have the harness spliced on already, if so just cut at the splice and reuse.
