Hi I've just bought a JVC KD-G343 CD/MP3 player and went to halfords today to get the iso wiring adapter PC2-08-4 for my car (2000 Fiesta W972 PLJ). However it doesn't fit into the back of the cd player although it looks like it should. Returned the adapter and tried another one but apparently the connectors don't fit as they are only split one-way and should be two-way. I've sent a couple of emails to car audio retailers but has anyone else had this problem? I don't want to do any soldering just want to plug and play. I just don't know which one I definitely need and from where. Cheers
