Wiring diagram for underdash relays -- 95 Suburban
I have a relay that is constantly humming under the dash. Tone changes with engine speed (sort of sounds like when you are charging your phone while having it plugged into the radios aux input). Anybody have a wiring diagram of what each relay is for and what they control?
