Don't worry about the brown wires. They are for telephone mute.

The yellow is Memory (constant 12 volt, so battery is fine), but the red should go to a 12 volt source that turns on and off with the key.

SOURCE: Yellow Wire has no power

Your stock radio should have had a wire that does this. It may not be yellow so look up the wiring diagrams for your car. If you can't find it by doing that, then look up a diagram of your use box. Sometimes there's a diagram on the back of the fuse panel cover or somewhere around there that tells you what fuses are from what. You can then run a new wire if you have to.

Ford Ranger 1997 Radio Wiring - Yellow Wire ' Red Wire, Radio only powers on when both wires are intertwined together. Yellow Wire (Battery Constant) 12V+ and Red Wire (Ignition Switch) 12V+ intertwined...

The yellow is for the memory of the radio. It keeps the stations you program in. The red needs to go to a ignition on only. Other wise the radio will always be on, unless you turn it off every time with the knob. It is working because yo can hook them up and the radio works. Just find an ignition on wire...

After rewiring my Boss 636CA audio player, It wont light up or play music but will still take and eject my cds. Whats wrong?

you may not have 12 volts or 13.5 volt on all the wires.
you also may not have a good ground to the frame of the car or truck . check the wires at the radio harness will using a digital voltmeter if you can do this find a shop who can ..

red = switch ignition wire must have 12.0 to 13.5 volts when ignition switch is turn to run or accessory position
yellow = memory or b+ wire also known as constant power this wire has power on it at all time even when car is off that is what save station presets and clock display ... must have 12.0 to 12.5 volts at all time when the car is off. will display 12.0 to 13.5 once car or truck is running.
black wire = is your ground wire the metal surface you chose to make your ground wire location. must have the following..

1 clean and bare metal not paint or grease on area you will attach the wire.
2. area must be connected to the frame of car or truck
3. good crimp connection and tightly secured to the area your mounting wire with a bolt and star washer etc...

with out a good ground you will not complete the circuit properly
strange things will happen
poor functionality
works intermitting

now if you check everything and everything is right and still nothing the display on your radio is bad .. or maybe needs a boss service tech to check it out because some wrong with the radio itself

There are 4 wires. Red, Yellow, Orange and sometime yet another lower amperage yellow. Oranges is rarely used anymore. (Dimmer) Yellow i believe is constant (Always a little trickle to keep memory_. Red is for switched (ignition).

I installed an older used stereo. I found the red wire is power, the black is ground, What is the yellow wire with the 5amp in line fuse for

The Yellow is your Ignition wire, It controls the stereo power when the vehicle is on/off. It can be spliced with the red wire, however I wouldn't suggest it unless all other options have been used.

The radio will not hold memory

If your radio will not hold memory then you are lacking a constant 12 volt power source. Check the yellow and red wires at the radio. The yellow wire should be connected to a constant 12 volt power source (battery) and the red wire should be connected to a switch 12 volt power source (accessory or ignition).

I install a radio it dont keep a memory

Pull the radio back out. I bet you hooked up both power wires (red and orange or yellow) to the ignition on hot wire. Orange or yellow depending on the radio usualy goes to the ignition on hot wire and red to a constant hot wire. Check the radio wiring diagram or list. One of the power wires has to go to a full time power source. check the wires with a circuit tester with the key off till you find the constant hot wire (battery power)
