Question
RECENTLY INSTALLED NEW SONY CD DECK IN MY TRUCK, HAD A INFINITY CD PLAYER IN IT. I INSTALLED IT AND THE FOLLOWING PROBLEMS HAVE OCCURRED. 1)NO MEMORY TO DECK, HAVE TO SET CLOCK EVERYTIME AFTER IGNITION TURNED OFF. 2)OVER HEAD LIGHT DON'T COME ON UNTIL KEY IS PUT IN IGNITION AND TURNED ON, SAME THING FOR POWER LOCKS. 3)AFTER IGNITION IS TURNED OFF THE HEAD LIGHTS FLASH, LIKE I ACTIVATED THE DOOR LOCKS. WHICH I HAVEN'T. I DO HAVE THE SCHEMATIC OF THE WIRING FOR THE FACTORY INSTALLED RADIO (16 WIRE). OTHER THAN THAT RADIO WORKS GREAT AND CD PLAYER. PLEASE HELP

Answer
The yellow wire from the deck isn't connected to constant power. This is the memory/time wire.

In some vehicles, certain features are wired through the radio. eg. in my '97 Civic I had to get a special wiring harness just to keep my keyless entry working. This involved my stock radio to be shoved into the dash with the aftermarket radio as normal. You may suffer the same fate.

You can get the right harnesses and install kits from here http://www.metraonline.com with instructions.
