basically- do i have one? im going to install a switch for some reverse lights i added to my truck. so im trying to figure out the best way to power the switch. i know it would be easy to just run it to the battery, but im not sure if thats the best way.. ive read that some trucks have dedicated accessory fuses for this type of thing, but i dont know if i have any. much less what port it would be

anyone have any suggestions on how i should accomplish this?
