  • Use your preferred method to properly connect the wires to the black and gray connectors from the install kit to your aftermarket head unit wiring.

Step 4: Check Fuses & Test The Radio

  • Before plugging in the new harness and radio to test it out, check the fuses to make sure they are good for your corresponding year model.

  • Connect the last connector to the radio and set it aside.
  • Reconnect the negative battery cable.
