These are the D21 wiring details. The best way is to get a conversion harness D21 to JVS from Crutchfield.

Hi, you can usually buy a stereo wiring harness that plugs right into your car and they are color coded to match the standard aftermarket wire radio harness, all you do is take the plug from your new stereo and match the wires with the adapter, just connect the matching wire colors. it's super easy and well worth the $15-20, and you don't have to cut up your factory harness.
good luck!

Hope this is what you are looking for and hope it helps....Good luck.

Try going to the crutchfield website and look for help installing stereo. they can get you vehicle specific wiring codes for free. Also, almost everey stereo has common color codes for wiring. red- switched batt. +, yellow-constant batt. +, black= ground, blue- power anrenna, etc.

If you need further help, reach me via phone at https://www.6ya.com/expert/david_f2436a37cbb50365

Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.

no wiring diagram needed go cut a plug from a junk yard and wire it into the cut wires then buy the adapter kit for you car and wire that to the car plug and the radio plug.
