after replacing the switch the lights still don't come on. Is there a fuse or relay and where is it?

had problem with my truck randomly sputtering like it wasnt getting any gas. replaced fuel pump,fuel filter,and rotor cap. fuel pressure good {20}. still sputtering. then i pulled the vacum hose on the air filter because the flapper was closed.runs little better but what is the relation with the vacum causing the flapper to close and not let air into the carb. is it a tranny issue ?
