Had factory radio, burned out or so I thought. Replaced with after market, not the first one in there. Bought wire harness so I did not need to cut any wires. Now I have no power to the new deck. Fuses are good, deck gets power when connected directly to battery. The only ting not getting power is the radio. Any thoughts?

Go back to factory wires and make sure you get them right. I'm assuming the factory speakers are still connected to the harness. If the new radio was smoking, it is gone. Get another one. Let me know if you need more help.

check the radio stores as you may be able to get a radio harness to connect the aftermarket radio to the factory wiring harness so you won`t have to cut and splice, its just a plug and go.

most of these car the plug is simply a plug for convieince you dont need it to hard wire it you simply match up the colors most of them will be the same and then if there are any left over you should be able to do process of elimination hope this helps

Make sureyou didn't accidently unplug any vacuum lines when you had your hands inside of dash.

buy a harness .. much safer , without cutting factory wires

go to autozone and get the radio wire kit it tells which wire goes where

run any power wires directly to a post on the fuse block. yellow or orange needs power all the time even with the key off for the memory. the red wire should be on a switched terminal. THe factory radio wires have many other things that may come off them that may effect performance. You can buy a fuse tap at the same location you got the harness, if you need more help just post back, I will watch for any questions.

see an auto sparks ,or take to a local radio fitting shop ,no good telling me here because colours of wires can vary between manufacturers of both the radios and the vehicles

I have seen people remove the factory radio, cut the harness and splice it to an aftermarket headunit, then attempt to reattach the factory harness they cut off to install the OEM radio back in proir to sale. Try removing the radio and look to see if the wires have been tampered with. If so you need to reconnect the harness wire by wire and use crimp connectors not the twist and tape method. Otherwise the electrical system has been altered elsewhere. The ACC lead to the radio should power off the radio when you turn off the ignition no matter what unless the electrical system has been modified.

With that year vehicle it is recommended that you use a special harness because it has an factory amp and in order to get the proper wiring it requires the harness also if you don't use the harness you will loose your onstar and vehicle chimes and warning sounds.
