I recently bought a used Toyota Tundra with four auxiliary lights installed. These are wired on two different relays going to the stock auxiliary light switch on the light arm on the steering wheel. I added an led lightbar and tied it into one leg of the other four lights. Worked perfect until yesterday. Now the two original lights on that leg do not work either. All I can locate are two relays for the lights. Is it possible that a blew a relay? No inline fuses to be found. Help please.
