Retained Accessory Power (Radio Stays On Until Door Opens)
Last Updated: November 28, 2006

Retained accessory power is when you turn the key off, and the radio stays on until you open a door. This can be great for ejecting a cd, or to rock to the last minute of that song on the radio. I did this on a 1994 Beretta but it should be similar for other models as well. I drew up a diagram to show how to hook this up.

Parts needed:
Two relays
Wire
Misc. connectors


Now if you follow the diagram the (-) door trigger can go on the negative side of the interior lights. On my 94 I ran into a problem, when you turn the key off and take it out of the ignition, the lights would come on. This kind of defeats the purpose of the mod but I found a way around it. The convenience center is located under the dash near the fuse block. Find the wires Green/Yellow for the driver side and the Light Blue for the passenger side, use those wires for the negative trigger.
