Audio connection

Ive just replaced my stereo with an after market one (I have the plug and play ISO connected variety so was easy)
question - above the standard ISO for speaker and power etc, is a small yellow plug with a couple of wires in it plugged into what looks like an ISO slot (same width) but isn't
whats that for? something pre-wired? do i need what ever it was for? (Stereo seems to work just fine)

anyone know what this interestnig connector does (or did when it was connected to the factory system?)

Steering wheel controls???

maybe.. pre-wired or something (I don't have steering wheel controls personally)
Just interested really as I don't think Im missing anything. All the functions work (perm live, ignition live etc)

If it's regarding an l322 it could be the cable that goes to the in dash center speaker ??

see my sig..p38

Yellow wire on car stereo is normally the switching supply for an amp.

ITs not a yellow wire, its a yellow CONNECTOR BLOCK - can't remember the wire colours of the 2 wires in it, but its not plugged into anything now and I don't see what difference its made. Maybe I will take a pic and post it or something

factory hands free kit or traffic master just guess.

TAH,

Does the back of your old head unit look like this?



If so, I presume the unidentified yellow plug is fitted to the top socket.

If it is, then it's for an auxiliary audio output for an amplifier, which you probably do not have fitted.

the light is shed..yes looks like that, yes was connected to the top connector

not connected now as there is nowhere to connect it on the new one.. hey ho
