Heres the wiring diagram so you can see what connections you do have. 3 outputs to the CD Changer called remote radio outputs.

The brown wire works. I found that it was a tad busy in there and sometimes I'd get a power interrupt. Just a bad connection on my part I guess.
Here are other options for ACC power
The easiest is to use fuse #22 which is live but not used for any other function. I used an “add a circuit” connector to hook in. This gives you the switched hot.
These are not my pics but show you the hook ups
You can see how the connectors slot into the fuse box/
The other option is to hook up into the spare connector which is available for ancillary devices. I believe this is used for the CD changer so it may not be an option for you if you have one of those fitted.
In the passenger footwell (unless you have a 2004) behind the kick board you’ll see a fuse block and to its left a silver box which is the BCM. There are three wires taped together feeding into a connector.
The Black wire is ground; the Orange wire is powered through fuse #7 but is permanent hot. The Yellow wire is powered through fuse #11 and is switched hot when the key is in the ACC or ON positions. Hook up to the Yellow for switched ACC.
