Headlight relay system and Convertible top relay system recommendation

matthon said
On his headlight kit, does anyone know if there is a specific reason power is taken from the alternator, as opposed to the starter relay or battery?

Which item powers the car with the engine running? Also, the charging system issues if you don't have other components to address the mopar inadequacies.

Thanks for the comments, I try my best to provide great products at a fair price.
