i have an 05 balt lt trying to hook up new head unit bought best but connecter for 20$ all hooked and they told me hook red wire up to power and when i do my gauges go crazy and have no sound any one have this problem? any adive would be great!

 

Red wire is for the turn on lead, you need to get a fusetap and tap the sunroof fuse on the passenger side fuse box.

 

so u mean hookj all 3 red wires togeter and run lead wire to fuse box, im really stuimped never done this before

 

What 3 red wires? Please tell me you didn't feed power into the car's harness?

The only red wire you should be messing with is the one coming out of the harness of the new CD player. You need to hook that wire up to switched power for the radio's turn on signal. The easiest way to do this is like xav said, use a fuse tap on the sunroof fuse.

 

there is a red wire from cd player and on the new harnes so i hook up red wire from cd player to sunroof fuse what do i do with the other red wire?

 

Man, drive to an audio store and pay the bones for them to install it before your fry your car.

 

exactly, its not worth freaking up something because of user error, it will be alot cheaper in the long run

 

what other red wire? throw some pics up man.

 

i'm with them go get it looked at...

 

the switched ignition (red wire) wire on the harness you bought lines up with a LAN (data wire) wire.

by a relay and wire it to the low current accessory (brown) wire, that way you have radio on in ign & acc. key positions.
