Head Lights On All The Time When Car is On
On my 1991 GTA Trans AM it was a system in it that would turn my head lights on if a sensor would notice that it got dark out. Well I went to change my dash speakers one day, and ever since I did the speakers, my head lights keep turning on, and staying on even in direct sun light.
And one know what could be my issue? I see that there some kind of sensor on the dash passenger side just past the defrost vents. I tryed monkeying around it, but nothing changed

Sounds like someone added an auto headlight system in your car. Not forsure how it was installed but the sunlight sensor must of got moved into darkness. Sounds like the thing on your dash is probably it but wouldn't know without seeing it.

Light Not Right
The most likely cause is:
You broke the connection to the Photoresistor.
Inspect the connection.

If My Engine Has An Illegal Part, And The Inspector Doesn’t Hear It, Does It Make A Sound?

required by law in Canada so was std fitment on all Canadian export models '90+
Canada Motor Vehicle Safety Standard 108 specifies requirements for the mandatory fitting of DRLs to vehicles built or imported after Jan 1990.
