Confused about car stereo connections..
if it was me – for minimal fuss id just get an iso to go into the back of the JVC and chop it to make it fit whats in the dash already.
failing that i would just go into halfords with the stereo and the current plug and get one to fit between them
ordering it online is going to lead to alot of tears and wasted time/moneyPosted 4 years ago
I’ve just found a picture of the back of the Sendai 688;
That’s definitely not the same connector as shown in the above manual, looks like an ISO connector to me. Which means, it should fit the JVC. Except, the picture that the JVC guy sent me, it definitely wouldn’t fit. The JVC looks like it needs one of these 20 pin connectors;

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..

then you need to do it the old way, wiring diagram, set of cable strippers and a roll of insulating tape…
I agree, looking at the picture of cd… top 8 are speaker wires, these probably won’t change in the new plug.Posted 4 years ago
Bottom 4 will be;
permanent live (+12v)
switched live (on off with ignition, saves radio setting ect)
Ground (earth) CD will work with only these 3 wired up
Last one is possibly some light dimmer thing, or electric aerial supply, depending on cd.
Easiest way of finding out is to plug wiring harness in without cd connected, using a multi-meter test each of the 4 lower wires to work out which is which.
