I have a plug in my bed to run lights/brake on gooseneck trailers. I discovered both of my 30A upfitter switches are wired into this plug. I'm still have the two 10A upfitter switches vacant but I don't know if they can handle the bed lights I'm wanting to put in my bed.

Could I just splice into one of the 30A wires (it would make the install so much easier since the wires are already there)? I pull a gooseneck once in a blue moon so I'm not worred about pulling to many amps.
