This is kind of Weird, Problem with Electric System

[woundsofchrist]

Well, I'm new to this forum. I love my Toyota Supra. I owned one when I was 16 and recently I purchased one. I now own a 1986 Supra MK2. It's a really nice and powerful car and I got it good for the price as well. Well here's the problems I've been having. Yesterday I removed the OEM car stereo that was still in tact in the car and put in a better Sony stereo. Well the first thing that it was doing was whenever I turned off my light switch the tail lights and headlights remained on. And the lids for the headlight were not open. Now somehow that problem got fixed. I can turn my lights on and off at will now. My lids however do not go up. So I was wondering if there would be a relay that can be affecting this. I can manually set my lids up and when I turn off the light switch they go down fine. When I turn on the switch again, they don't seem to even move. Any help is well appreciated.
