- Using a wire stripper, strip about half an inch of insulation from each wire.
- Solder the wires from the harness to the wires on the aftermarket radio. Make sure you connect the wires according to the wiring diagram.
- Wrap each soldered connection in electrical tape, to protect it from moisture and other elements.
Step 2: Remove the Factory Radio
Next, you need to remove the factory radio from your Altima. Here’s how to do it:
- Use a set of screwdrivers to remove the dash trim panel around the radio.
- Unscrew the screws holding the factory radio in place.
- Remove the radio from the dash and unplug the antenna and wiring harness from the back of the radio.
Step 3: Connect the Wiring Harness Adapter
Now you need to connect the wiring harness adapter to the wires in your Altima. Here’s how to do it:
- Connect the wires from the wiring harness adapter to the corresponding wires in your Altima, using the wiring diagram as a guide.
- Plug the antenna and wiring harness into the back of the aftermarket radio.
- Slide the aftermarket radio into the dash and screw it in place.
- Replace the dash trim panel around the radio.
Step 4: Test the Radio
Finally, you need to test the radio to make sure it’s working properly. Here’s how to do it:
- Turn on your car and the radio.
- Check that all the speakers are working properly.
- Test the radio’s features, such as AM/FM, CD player, and Bluetooth, to make sure they’re working as they should.
