NO question is Dumb

Everyday, is a learning process.
when wiring a dual filament turn signal think about what it will do and look like to others...
Sounds funny huh?
if you wire the parking bulb to the dimmer of the two filaments you will
always see it 'on'.
You then wire the turn signal side to the brighter filament. so even when the truck's lights are on ...
You will
always see the turn signal flashing brightly in the day/night.
Ps It grounds thru the grill to the lamp holder. that works fine. if needed just scrape the bolt area w a bit of sandpaper.
