I have a 91 lx5. 5.0 attached to the left side of the hood is black electrical box at first I thought it was an under hood light but I see place to put a bulb any thoughts?
It's a mercury switch. On when hood open, off when hood closed. Make sure it's not unplugged where the wire exits the hood.
They changed them after '88 or '89. Mine doesn't look anything like yours & uses a different bulb.
