radio wiring

Generally speaking, the anti theft function is only to be found on those radios fitted at the factory. After market ones like the Sony mentioned by the OP do not have this feature. Even if the anti theft function is present, it pretty simple to input the code when you turn the radio on.....

There was a recent thread on a similar subject just recently. I suggested connecting a 9v PP9 to the 'always live' wires. Haven't heard whether it worked but it might.

Car radios sometimes draw as much as 200ma when 'off' with the yellow wire connected. Not the kind of thing to leave connected to your batteries over the winter. ( or a pp9! )

Car radios

The OP needs to confirm if there is a security code needed. If he doesn't have it and it is needed then throw the radio away. If he has the code then there will still be a fair bit of button pushing to get the radio to work if he has cut the keep alive power when away.
I tried a digital tuned car radio in my boat with minimum electrical power (charged by a 5w or less solar panel) The radio keep alive current did flatten the battery though of course OK for cars and boats with more power.
To my mind the ideal is an older mechanical dial car radio. If you can find one. It is the perversity of our day in electronics that complexity is often cheaper to make than good old mechanical.
As for the security code. My 12 year old car had a security code for its radio cassette player. It must have been the era when car radios were worth pinching. It seems they are so common now that they are not worth pinching so modern cars don't have security code. Or perhaps it is that the radio is now built into the dash and electrics such that it is not suitable for other cars. Anyway new car does not have security code.

I have gone to a portable radio or none at all just for simplicity. good luck olewill

When fitting a car radio, always plug the aerial in before powering up, or you may cause permanent damage to the set. I have done this once.
