No headlights, taillights, or brake light

Electrical problem 6 cyl Two Wheel Drive Manual n/a miles

I have been having this problem for a few days now. None of the lights work except for my turn signals and hazard lights. In fact. Nothing electrical works in the truck at all. Only the gauges. And that's because I changed the fuses out to get it to work. Otherwise, the radio doesn't work, the dome light doesn't work and the cigarette lighter as well. But my main issue is the headlights/taillights. I checked the bulbs, they're all good. So I looked under the hood to find the relays, and I only found two relays in the whole truck. I was told that there are no relays for the headlights on this year and model. But I checked anyway. The two relays that were there both would click one time when hooked to power. And also, I replaced the headlight switch with a brand new one, 99% positive that it would be the fix, only to be disappointed again. I've run out of ideas. Somebody help me out here?
