Ok i have a 99 ram 1500 4x4 5.9l. I got a pioneer supertuner deck from a friend at work with a adapter harness. So i was out one night seeing if it worked, i had my dome light on, and when i hooked it up my dome light went out. And now my radio, dome light and cargo light arent working. I think it might have something to do with my seats to because when i have my truck off, the belts are locked and when i turn the key on you can hear the relays in the seats click and they unlock. Does anyone know if theres a inline fuse that mightve blown?? i cant figure it out and im goin crazy without it.
