I am hooking axillary cargo lights up to the back rack of my truck. I'm going to hook them to a switch on my dash simple enough. but I would also like to install a switch in the box of my truck. I would like to be able to turn the lights on from inside the truck or outside the truck. I know how to use relays I know how basic wiring works just looking for maybe some diagrams. I just want to make sure I do it properly I'm using led toggle switches and I don't want any back feed. I'm wondering if I can run the wire from each switch into one relay but just want to be sure. Any thoughts or ideas would be greatly appreciated thank you
