I expect it's this
I just bought one of the all-in-one Chinese 7" 2 Din unit thingos. Just wondering if I will need a standard ISO harness for my car or one of those advanced ones? (I think they have RCA connectors but not sure). The unit comes with both the standard ISO and RCA connectors so I'm not sure which one to use.
You will need to connect all the wires from the harness for your vehicle to all the wires from your headunit.
If you have issues connecting wires together, you might consider having a professional install your gear.
Yeah which is why I was thinking about going for the second option. The unit comes with an ISO harness so it should just plug right in yeah?
there is no standard connection type in car audio. every manufacturer uses their own style of connectors, so you must connect the wires together from the adapter harnesses to get the correct configuration for your purpose.
Sorry but I don't quite understand.
I do realise that each car manufacturer have their own wiring but I thought these wiring harness adaptor converts this into a standard male/female plug that can be plugged into another unit using the same standard male/female plug?
the ford-specific connector in your car should be completely different from the chinese unit's connector...
you should be able to get a adapter cable for the ford harness+ connector, and the chinese unit should include connector with the wires hanging off it-- you would need to connect those 2 harnesses together.
butt connectors are common for this-- just make sure to fully crimp them so they don't fall apart later on. otherwise, i prefer to solder my wire connections.
Also, no offense, but maybe Darque is right: if you are that relucant to do one of the most basic functions of upgrading any radio in a vehicle, should be messing with it at all?
Maybe paying someone is the right way for you to go. If you have friends that do this stuff, beer can go a long way to getting help just wait until it's in and working before offering too much!
