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

 

Look up three-way light switch wiring. You will need two SPDT switches

Ya im trying to do it with, spst self illuminating toggle switches. so it matches my custom switch panel. I want it just on/off from the box of the truck. And an extra on/off from the cab of truck. Both able to switch the same light. So its not really a "3 way switch" . Cuz if one switch was on the other switch would not do anything
