No they are not hooked up to one fuse.You may have shorted something...Could you take a picture of te wire connections where you wired your radio?

all i did was connect all the same wire colors together, like yellow with yellow , green and green, and also i have illumni wire on the new deck wiring harness and its an orange and white wire i connected it to the orange wire which is the dimmer wire for my gm wirirng harness that comes with the car, so maybe it has somethign to do with how i hooked up the wires i cant take a picture cause my boyfriend has the car at work so but i did some research and noticed that i only need the speaker wires left and right postive and negative connected, i ineed 12v wire connected circuit switch wire connnected and dimmer switch wire connected and i think i hooked the dimmer switch wire to the wrong one on the new decks wiring harness, so i wantedd to re wire but have to wait til hes home im reallly hoping that will work cause i already bought a new dimmer switch because i thought the fise was blown on that

Yeah if you think that is wired wrong and want to retry it wont hurt anything(more) im not an electrical guru i know enough but not all lol but i am trying to help the best i can

yea i know so much just wish i knew wat the problem is i dont want it to be notthing big or expensive, im hoping its the way i wired it or a fuse cause the sensors dont detect when its dark out and i dont know why

yah if it affected that many things sound like something is wired wrong.

alright ill check it out and keep u upated thnks
