Wire One Rocker Switch to control three separate harnesses

How would I wire one rocker switch to control three to five harnesses/lights already controlled by individual switches?
Specifically 4 pods, 1 52 inch double row, 1 20 inch double row.

Thanks!

Relays.

I am assuming you want a master switch to kill power (or supply) all at once. Wire one relay with the output supplying everything else. Determine your load and size your relay to max load and fuse accordingly.

 

Does it make a difference if there are relays in the harness already? Anyone have a wiring diagram for this sort of thing?

 

Couldn't find a diagram showing multiple relays, so I'll reference the one below. What you need to do is connect the "load" (output) of your single switch to the "86" (trigger) input on each of your relays. It can be a pain in the ass because there is no standardization of wire colors or relay pin numbering in the aftermarket. Be patient and label the wires before you start cutting and splicing.

 

Awesome thank you!

 

You'll be cursing soon if your experience is anything like mine working on @tyfoon11 truck.
