You should have 6 wires coming out of the hazard switch. One of those is red, that leads to hazard flasher. From FLASHER, there are 2 more wires(pink) one pink goes to brake light switch(attahced to pedal). Other pink goes to fuse block...check brake light switch. Also make sure wires to hazard are in proper spots.
