Hi guys, just bought a 78 bus and it has 4 relays beneath the 12 fuses. Can anyone tell me the purpose of each of the 4 relays left to right?
    I found that the hazard switch is damaged and have ordered another one. Right now only my hazard lights, blinkers, and reverse lights are not working...and the headlights, bright and dims, parking lights, and brake lights do work. Thanks for any info!
