   Step 2: Purchase additional accessories.

   For a successful installation you will need some additional pieces that may or may not come with your stereo.
   
   You should make sure to get a trim plate for the outer face of the stereo.
   
   A DIN cage or mounting bracket may be necessary to secure the stereo to your dash.
   
   You should also purchase a wiring harness adapter so that you can plug your new stereo into your car’s electrical system., This list can change from vehicle to vehicle, but the basic tools include: screwdrivers, wire strippers, wire cutters, and electrical tape.
   
   You might also need a panel remover tool and factory stereo removal pins depending on your vehicle. , This can be very helpful in knowing exactly which pieces of dash to remove and how to remove them.
   
   If your owner's manual or service manual does not provide the details you need, you might try looking for a Haynes Service Manual for your car., This is the negative, commonly seen as the black terminal of the battery.
   
   You never want to work on your cars electronics with this connected as it might result in damage to the electrical system or injury to yourself. , Using the manual from above, determine which pieces of your dash must be taken off to remove the factory stereo.
   
   These pieces may pull right off with a panel remover, or they may be held on with screws, bolts, or clips. , Once any necessary pieces of dashboard have been removed you can take out your stereo.
   
   Sometimes the stereo is bolted or screwed onto the dash and sometimes you will need to use special tools that are inserted into the face of the factory stereo to release it from the dashboard.
   
   This procedure will vary from car to car. , If you opted out of buying a wiring harness adapter, you may have to cut the wires instead of just pulling them out.
   
   Some vehicle manufacturers may void warranties if wiring is cut.
   
   Cut only as a last resort. , The aftermarket wiring harness adapter is specifically designed to fit your vehicle's wiring harness.
   
   This allows you to simply plug the new harness adapter into the factory radio harness and makes wiring your stereo fairly straightforward. , The new radio will have a plug that must be spliced to the wiring harness.
   
   The harness adapter and plug are made to go together easily.
   
   This adapter set up will allow you to plug the car's original wiring harness into your stereo.
   
   A few quick steps is all that it takes to connect the new stereo plug and wire harness adapter.
   
   Match the colors and sizes of wires on the plug to their identical counterparts on the wiring harness adapter.
   
   Strip approximately two inches insulation off of all of the wires and twist matching wires together.
   
   This provides superior surface area connection to crimping and more flexibility than soldering.Cover the splice with electrical tape or a twist on wire nut If you have any trouble matching the wires, follow the steps provided with the wiring harness adapter.
   
   The wires on the harness adapter and plug are usually color coded or tagged for easy identification and matching. , Now that the wiring harness adapter is plugged into the wiring harness and attached to the stereo plug, all you need to do is plug it into the back of your stereo.
   
   Now the wiring of your stereo is complete! , This step will differ with each car and may require first sliding in a DIN cage, or simply mounting the aftermarket stereo onto the original mounting brackets. , Make sure no wires have become disconnected or pinched.
   
   Reconnect the negative battery terminal and power up your vehicle.
   
   Make sure that all features of the radio and all the speakers are working. , If it doesn't work, you likely have a loose connection or have joined the wires incorrectly.
   
   Disconnect the negative battery terminal and troubleshoot.
   
   Make sure that the original wiring harness and aftermarket wiring harness adapter are securely attached.
   
   Make sure that all of the connections between the aftermarket wiring harness adapter and the aftermarket stereo plug are correct.
   
   Double check with the manual that came with the aftermarket stereo or adapter.
   
   Ensure that the aftermarket stereo plug is properly and tightly plugged into the back of the aftermarket stereo. , Once the new stereo works, secure it into the dash and put everything back together.
   
   This is the same way that dash was disassembled, but in reverse. , If you unplugged the terminal again after testing the battery, you can reconnect it now. , Your installation is complete and you can show off your new aftermarket stereo.
