After market Radio wiring questions, Wiring locations for after market digital media players Options

[pgollender]

I decided to update my fuse box with a J-West box. ( Much nicer) and at the same time install an after market SONY digital radio. I need help with where to locate or "splice"
the new wiring.

There is a yellow 12V power wire that supposedly stays on all the time as you dont lose your presets.
A red wire that is the 12V "Key On accessory wire"
and an Orange/white wire that is an "illumination wire" that dims your new radio lights when the headlights are activated.
Where is the best place to attach/splice/locate these wires ?
Last time I added an after market radio was pre-digital and just attached the one radio line to the cigarette lead.

I ran the illumination wire to the gauge lights with my Alpine. It works, but not very well. For the ignition wire, I created an accessory switch using a single pole double throw toggle switch. Switch up allows me to listen to the stereo without the ignition being on. Switch down, means that the stereo will only come on with the ignition on or when the car is started. My ignition connection comes from the cigarette lighter and the battery connection comes from the fuse box. I also put an amplifier in the front trunk and have an electric antenna.
