Want to replace the Sendai 688 I currently have, with a JVC R KD303 I've found cheap online.
According to the manuals, the Sendai is 20 pin;
And the JVC is ISO
The cable diagram for the Sendai shows an adapter from ISO to 20pin, but I'm pretty sure when I opened mine up there wasn't an adapter, just a bunch of wires taped together (assuming that was instead of the proper connector).
I'm assuming I will need to get an adapter then, to run the JVC stereo with my current wiring? I've searched around but can't find anything suitable..
