I'm not sure if I am posting this in the correct section or if it should be in the audio section, if its in the wrong section I'm sorry.

My '85 Trans am has a benson 4010k radio deck in it and whenever the headlights or the parking lights are turned on, with the car completely turned of the radio comes on.
Also the parking lights are permanitly on when the car is on, I figure this has something to do with the whole wiring of this radio

 

YEs easy fix. the radio acc wire RED wire is wired up to the headlights. so when they r on the radios on. easy fix. Find a fuse that turns on with ignition. Run the Radio ACC wire to that fuse and there radio only turns on with key .
