If there are no holes, remove the trim below, above or to the side of the stereo to gain access to the bolts. Use an inline fuse. A fuse in its ground would have blown to protect the radio. After you have removed all of the trim surrounding the stereo, you'll remove the old stereo as an assembly, a unit that includes the stereo itself and a mounting bracket. There may be a trim “faceplate” over the stereo that pops off, revealing bolts in the face of the stereo instead of behind it. Once you’ve connected your radio wires, secure them with solder or heat-shrink wrap. Remember your first question? With the bracket assembly out, you need to remove the old car stereo from it.
Once you've checked the power and all of your speakers, unplug the stereo unit. Use the screws that came with the new car stereo; they will be correctly sized.

The 12 volt constant power wire is usually yellow or blue, though it may be a number of colors coming from the car. Now all you need to do is put the new stereo into the bracket.

The wire which has lost power is known as the ignition feed and the wire which has retained power is the battery or permanent positive 12v wire. Try not to let the wiring get in the way of the bracket you will need to bolt the stereo too (if your stereo requires being bolted into place).
You do not need to remove the battery or disconnect the cable from the positive terminal. If they are present, your stereo is held in place with spring clips.
Soldering two wires together requires a soldering iron and solder. Use the diagrams to properly match each with its appropriate wire from the car. Set the trim aside where you won’t accidentally sit or step on it as you work. You melt the solder onto the wires to stick them together and as the solder cools it forms a permanent bond. This likely because you didn't connect to the red ACC wire. Some vehicles may require an adaptor to properly fit the new stereo in the hole for the old one. The engine to chassis bonding wire had broken. Be careful when removing the wire harness clip from the back of the stereo.
