Hello guys, I was wandering which wires to connect to which, when I install my jvc KW-V230BT into my car. Do to carelessness I didnt know to buy a harness, so I had cut the wires connected to one of my cars plug clips (the white clips that goes into the stereo). Now I'm struggling to see which wire to connect to which because the wires for my car not all of them match the same color for my jvc. Can anyone please help.

I'd recommend reconnecting the original harness and then buying the adapter harness and wiring up according to the guide. If you want to connect straight to the JVC's wiring harness, the service manual will give you the color conversion.

I don't see where in that service manual that you provided about anything regarding installing a aftermarket stereo or wiring conversions

Actually I think I see it, but it's confusing to understand it

Which is why I'd recommend reconnecting the OEM harness to use the proper aftermarket harness.

OP judging from your questions I recommend taking your car with the original harness to a reputable professional installer. Might cost a bit of coin but if done correctly I promise it'll be worth it to you in the long run.
