So i'm having a moment here. I want to wire a relay to send power to the back of the truck can't the description is a bit vague. Relay No, i don't need that much capacity but i figure why not. ...
I don't know, maybe I'm not understanding what he's trying to do, but your going to need a switch to operate the relay anyways (otherwise it's always on or always off) so just get a switch of the proper size and be done with it.
